Dappy has said that he is devastated by the decision:

"We wanted to go on The X Factor to be with Tulisa on Judges' Houses but the people who own it thought we were too much of a gamble, that we wasn't right. Instead Tulisa's been given Jessie J. That's cool too. Jessie is amazing, she's great, and we love that. But still the whole thing is wrong. I'm devastated they don't think we're capable of going on there and helping her."

The rapper, who has been working on a solo career, has said that the move by Cowell is a joke and that he should "watch his back":

"Gary Barlow chose Robbie Williams and he got Robbie Williams. Tulisa wanted me and Fazer but didn't get me and Fazer. It's a joke...Simon, I'm coming for you, bro. I don't care, I don't give two s**ts - you've made a big mistake, man. Watch your back, Simon!"

Check out Dappy on BBC's Never Mind The Buzzcocks and an interview with them earlier this year for the TV show OK!:

The young N-Dubz star is currently working as a panelist and mentor on the talent contest's new season and she told The Sun that she's putting her heart and soul into helping her group to succeed:

"I care about my acts and I want them to win. If they fail, I don't want it to be because of me. I want it to be off their own back. I want to give it 100 per cent and feel I gave them all the ingredients to succeed. I will be very hands-on with the final four. I'll do all I can to guide them and help — I want to win."

Although she knows it won't be an easy task, she already knows how to pick out the serious contenders and added:

"Those are the ones who spend the night rehearsing and then go straight to bed. The people wanting to fool around aren't taking it seriously. Fine, go celebrate once you're through and when you've got the time — but otherwise, don't do it."

Watch Tulisa deal with a rather irate auditionee on the current season of X Factor here:

The 23-year old N-Dubz star has said that once boot camp is finished in X Factor, maybe the three singers could come up with something:

"Gary’s already written a song with N-Dubz. I’m trying to get boot camp and judges’ houses out of the way before recording any solo material. But when I do, yeah, it would be a brilliant idea. I’d love to get Gary involved and even do something with Kelly, too, if possible.”

With only a couple of weeks left until boot camp begins on the TV show, maybe this idea could become a reality. Let's hope that poor Louis Walsh doesn't feel left out of all the fun!

Have a look at N-Dubz answering interesting questions from their biggest fans:

In a new interview with Company magazine, the current X Factor judge explained that she isn't afraid to be honest about who she is and that this trait is unusual in the industry:

"People forget the girls that look up to me come from the same background. I'm their role model because I'm the only celebrity that doesn't lie about the fact that she swears, gets into arguments, or was naughty when she was younger; just because I swear occasionally doesn't make me a bad person. It makes me human."

She also addressed the common accusations that label her a "chav" and said, "what is a chav? Supposedly someone from a council estate with a cockney accent. That doesn't make you a bad person. I haven't got a problem with myself or the way I talk."

"I've been put down a lot in my life and that can either make you depressed, upset and introverted or you don't care anymore."

Watch her handle an onslaught of criticism from a recently rejected X Factor contestant here:

The rapper believes he would fit in perfectly alongside quartet Will, Simon, Jay and Neil.

He said: "I'd love to be in something like the Inbetweeners. It's a great show and looks really fun to make. I'd go naked I wouldnt care. I'd happily get my bum out. I go skinny-dipping every time on holiday. I'm not afraid of my body. I'm the skinniest fat guy I've ever known."

Fazer also revealed he has already been approached to star as the lead in two British films.

However he is biding his time until the right role comes along.

He added: "I'm incredibly busy at the moment. I'm not sure I'm ready to take on a big role yet, I'd like to start off with something small."

Fazer, Tulisa and Dappy are taking a break from N-Dubz for 18 months to concentrate on other commitments.

Tulisa has replaced Cheryl Cole on the X Factor while Dappy's first solo single No Regrets is out next month.

Fazer's many projects include a collaboration with Katy Perry.

Chatting to promote N-Dubz's first live DVD, he said: "We're fulfilling all our N-Dubz commitments but then it's time to let our fans breathe."

Watch Fazer talk about N-Dubz in the US here:

The star, who is currently working as a judge on the popular talent competition, explained that she has big shoes to fill and doesn't want to be seen as trying to copy the 'Promise This' singer:

"I haven’t made any decisions about what I’m going to do musically because I’m just trying to focus on the job at hand. It’s a big role to take on but anything could happen. I’m not sure yet, I’m seeing how it goes."

She also addressed the recent reports that suggest she is imitating Cole's style and said that because she "is the most photographed woman in the country" there will always be situations where their outfits appear to be similar:

"People try new things and fortunately for her she was photographed doing it, so there’s always going to be pictures that you can compare between me and her."

Watch a contestant on X Factor pick a fight with Tulisa below:

The 'Playing With Fire' singer and current X Factor judge explained to Style magazine that becoming bad herself was the only way out and at least she was "content being protected":

"My way of getting out of it was getting in with this really hard crowd - the hardest of the hard in the area. We were a wild bunch of girls but I was content being protected."

"Yeah we did naughty things. We pinched a couple of handbags and got into fights I wasn't part of a girl gang though, we were just a bunch of troublesome chicks."

She also opened up about what she got up to as a teen and revealed that she lost her virginity at the young age of 14:

"It was naughty, people were smoking [marijuana] on their lunch break. I was one of the lucky ones to keep my virginity as long as I did. There were kids s**gging in the toilets at the age of 12 in the break time."

"When did I lose my virginity? I can't say too long, I was about to turn 15. It's the environment we're from, it becomes normal."

Watch a recent interview with Tulisa below:

Tulisa is currently working as a judge on X Factor and Dappy's solo career is already well underway, and now the third member of the 'I Need You' group is following his own dreams. He told the Daily Star newspaper:

"My album is going to do what Timbaland did. I’m in the studio this week with Katy Perry and there’s a couple of mega-stars coming up too.”

The 22-year old has big plans for the music he will put his name to and added, "I go into the studio now in a three-piece suit with a bow tie as it makes me feel special. It’s a frame-of-mind thing. If I feel like a million pounds that’s what I’m going to execute."

“Everything that leaves my studio I am confident is good enough to hit radio.”

Watch a brief interview with Fazer below:

The 'Spaceship' star spoke to BANG Showbiz after his set at yesterday's (July 10) T4 on the Beach and explained that as a rapper who's come "from nothing", he feels disappointed by people who allow teams of writers to create material for them:

"People who don't write their own songs shouldn't be allowed to be release them in the charts. We've come from nothing and wrote all our own stuff."

"Rappers who only feel they can rap and not do the chorus and let someone else do the chorus, that's cheating as well."

He added, "Do the whole tune, three and a half minutes by yourself and I'll take you seriously."

Watch N-Dubz perform 'Playing With Fire' from the weekend festival below:

Speaking to Choice FM, she explained that music is still very much on the cards despite her recent career move:

"I'd like to make a combination of things. I want to get on a bit of dance stuff. I'd love to work with someone like Swedish House Mafia, try something different."

"I also want to do acoustic things, just work from scratch with instruments whether it be strings or piano and just real melodic music. That's what I'd like to do. Some nice ballads as well. Because that's what I'm about really, growing up."

Watch one of N-Dubz's most recent group interviews below:

The 23-year-old singer and rapper told The Daily Star that now is the perfect time to branch out and develop his own career:

"There’s gonna be a Dappy solo album. There’s been N-Dubz and we’ve just done a massive arena tour, but the next thing is my solo album. It’s gonna be a big thing full of mental chart smashes."

He added that his debut solo single, 'No Regrets', will come out in September and also praised Tulisa, explaining that she will make a fantastic judge on the popular talent show:

"She’ll bring rawness, bluntness. She’s the closest thing to Simon Cowell on the panel. If you are crap, she’ll tell you you’re crap.” 

Watch a recent interview with Dappy here:

Speaking to Choice FM Breakfast, Dappy explained: “Tulisa is going to do her films and her fragrances.

"Fazer is going to produce half of my album and I'm going inside the studio to write songs with Tulisa.

"I've got bangers for you - I've got a big solo album coming for you, three smash singles. By Christmas, hopefully, I'll have two No.1s. One of my first ones is called No Regrets."

Despite the announcement, the rapper assured fans that the group would return, saying: "A year and a half or two years down the line and N-Dubz are going to be bigger than ever. We're going to come back and kill it."

Watch the group chatting about their single ‘Morning Star’ below:

Medical help was required as his ear was bleeding heavily.

Dappy, aka Costadinos Contostavious, told The Daily Mirror: 

"It was mental - check out the massive red mark she left on my ear.

"She leaned in for a hug, before going 'Raaaah!!' and getting me in a scary headlock. Then she just bit into my ear. It hurt so much, man!

"Then our security stepped in, put her in some mad lock and took her away. It does scare me, stuff like that, but that's what we set out to be with N-Dubz, that pandemonium."

Watch N-Dubz talk about their new single, 'Morning Star' and upcoming TV series, 'Being N-Dubz' on 'Freshley Squeezed' below: 

Dappy, real name Costa, explained that the 'Playing With Fire' stars have sold more albums than some of the previous BRITs winners, but they still don't get a look in where award ceremonies are concerned:

"The BRIT Awards see success in number one singles." 

"You get two number ones and you get quick status. They don't see album sales as a big thing and that's what N-Dubz are about."

"No one can beat our album sales. That's why the BRITs can do what they want. We've sold more albums than half of the nominees."

He added:

"There are artists who want what we have and we want what some of them have. We've only had one number one and we want more. But some artists would cut off their arms to have anywhere near the album sales we've had."

Watch the band's latest video for 'Morning Star' here:

Speaking exclusively to The Observer today, February 20, Dappy, real name Costa, explained:

"Going triple platinum isn't good enough, I'd like to go quadruple platinum. We've sold a hell of a lot of albums over the past few years, but it's about exceeding what you've achieved. It's easy to get there – but holding on to the success is much harder."

He also admitted that criticism and hurtful remarks, especially from people on social networking sites, does affect him:

"I get depressed. I've gone to dark places for days when I've seen our music videos have dropped off the TV airplay charts. Or I read a rude comment about us on YouTube. It fills me with self-doubt."

Dappy added that his career in N-Dubz probably saved his life:

"If I wasn't doing music, I'd be doing something illegal. Music and my dad saved me from either jail or death."
