The pair, who worked together on the smash hit single 'On The Floor', are good friends and during an interview with Ryan Seacrest on his KIIS FM radio show today (May 21), the rapper explained that he admires her work ethic and approach to challenges so adopted some of her ways as his own:

"(I) learn a lot from her every time I get the chance, I just watch how she moves. How diligent she is, militant at times, but very professional and a hard worker."

JLo and Pitbull reunited recently to record a song called 'Live It Up', which will act as her new single, and the track's music video has finally been released. Meanwhile, Pitbull has voiced a character for the forthcoming new movie 'Epic', which also stars Beyoncé.

The first single from their fourth studio album, 'Random Access Memories', once again sold over 100,000 copies to comfortably hold its position ahead of Passenger’s ‘Let Her Go.’

Demi Lovato entered at No.3 with ‘Heart Attack’ to score the biggest UK hit of her career, Macklemore & Ryan Lewis’ ‘Can’t Hold Us’ climbed to No.4, Rudimental's 'Waiting All Night' dropped to No.5, while Wretch 32’s collaboration with Shakka, ‘Blackout,' debuted at No.6.

Elsewhere, there were new entries for Sub Focus feat. Alex Clare’s ‘Endorphins’ at No.10, Stooshe’s ‘Slip’ at No.12, Olly Murs’ ‘Dear’ Darlin' at No.18 and Tich's 'Dumb' at No.23, while Mariah Carey & Miguel’s ‘Beautiful' climbed from 39-27.

The music mogul took to Twitter to muse about the upcoming season of The X Factor US.

After announcing the start date of audition stages and confirming details about the new panel,  Cowell dished out advice to people wanting to audition for the show.

He said: "We start x factor auditions in charleston on Tuesday. The new panel will be announced Monday. This is going to be an interesting show!

He added: And for anyone looking for advice on who too look to as an inspiration when you are auditioning for one of our shows. One name. Beyonce. And pink. And of course one direction. Who made it happen through sheer determination (sic)."

Cowell and Demi Lovato will return to the panel next season, with Britney Spears and L.A. Reid announcing their departure.

Cowell also reflected on his time at American Idol.

Randy Jackson announced he wouldn't be returning as a judge and mentor on next season's show - leaving behind current judges Mariah Carey, Nicki Minaj and Keith Urban.

Cowell added: "Randy leaving idol made me remember that Paula [Abdul] randy me and Ryan [Seacrest' had the best time. I miss them (sic)."

During a revealing interview with Billboard for the new issue's cover story, the 'Thrift Shop' hitmaker confessed that he was taking part in street rap battles when he was a youngster to try and gain respect from those already in the game: "This was pre-Internet as a way to get your music out. So I had to do shows, but I was too young. Freestyling on the street or in the park was where I honed the craft."

He went on to unveil his dark past, talking about how he often preferred drugs to school: "It was pre-gentrification of Seattle's Central District. And I wasn't going to class and I was doing a bunch of drugs and drinking. So my parents put me in a predominantly white school in the North End and then I did a program called Running Start, which was like a community college. I never got a chance to climb any kind of social ladder anywhere. I was more into making music-and doing hallucinogenic mushroom voyages."

Discussing his recovery, Macklemore (pictured below with Ryan Lewis) added that while he's clean now he still struggles with 'overindulging': "I tend to be an overindulger in general. Like I've just eaten two bags of chips and I had a shitload of candy from a gas station last night."

"I don't have moderation in my life. I really have to work on it. So with drugs and alcohol, I had no moderation. Smoking weed and drinking hindered my creative process. They were the veil over my eyes. It never really worked for me, in terms of being prolific."

Out magazine compiled the list and put Ocean at No.10, which makes him the only star of music to be featured.

He made headlines last year after writing an open letter in which he explained that he had been in love with a man. Following Ocean's honest admission, many other prolific music figures praised his bravery and spoke out about the changing attitudes towards sexuality in the music world.

Ellen DeGeneres was placed at No.2 on Out's poll, reporter and TV personality Anderson Cooper came in fifth and 'Glee' creator Ryan Murphy came third.

Rumours surrounding the teenage singer's involvement in the show have been growing since the summer and 'Glee' creator, Ryan Murphy, confirmed the exciting news via his official Twitter account earlier today (October 16):

"Michael Ausiello broke news of Jessica Sanchez on Glee. With voices like Jessica, Lea, Naya, Melissa, Amber, and Jenna...Streisand episode?"

Despite confirming that she will now be a member of the talented cast, no further information regarding the nature of her character or role has yet been revealed.

17-year-old Sanchez took part in the last season of 'American Idol' and finished in second place, just behind winner Phillip Phillips.

The 'Payphone' hitmaker, who has recently been working as a vocal coach on televised talent show 'The Voice', told E! Online that he enjoys watching 'Glee' and has spoken to its creator Ryan Murphy about possibly making a cameo in a future episode:

"I'm doing his other show now - it's the super dark, non-musical version of Glee, I've talked to Ryan a lot about [appearing on Glee]."

"We've had multiple conversations about it in the past, trying to find the right thing for it, so hopefully one day!"

He took to social networking site Twitter on June 13 to talk about his lack of respect for the controversial programme 'Toddlers and Tiaras', and wrote:

"I'd like to one day meet the mothers who allow their daughters to be on 'toddlers and tiaras' so I can vomit in their faces."

She attended a 'Glee' screening at the TV Academy of Arts and Sciences in North Hollywood yesterday (May 1) and fainted during a press conference, but following the incident she tweeted that it was a result of flashing camera bulbs:

"Hey guys, I'm okay :) I got a little dizzy from all the photog flashes! You'd think I's be used to it by now, still a red carpet amateur I guess. Gonna get checked out but I feel fine. Thank you for all the concern and well wishes."

Earlier this afternoon (May 2), she hit out at newly surfaced reports that suggest she has an eating disorder or is pregnant and explained that she wouldn't purposely harm her body to fit a Hollywood stereotype:

"Lol. Let me stop the rumor mill right now. I'm not pregnant! Yes I'm black but I don't have diabetes, I don't starve myself to fit clothes; I buy clothes to fit ME not vice versa, I DO NOT DIET; I eat right and exercise!"

"I love myself waaaay more than I like my career. I would never ever put myself in harm's way to mirror any "image". Come on ppl. Get a life. I did get a great laugh this morning reading all the BS though lol."

In an exclusive interview with The Insider, the actress explained that despite being included in the season 3 trailer that was released back in September 2011, she will miss being on the show and she's sad that her time there had to end the way it did:

"It is what it is. Lauren's somewhere in that school, she's just not on camera or being talked about [laughs]. She's involved in activities that aren't televised."

"Of course I miss me on 'Glee'. I miss everybody. I miss the fun experience that show is."

She also spoke about the flighty nature of the 'Glee' experience and revealed that getting cut is a possibility for any of the cast because nothing's ever set in stone:

" 'Glee' is very much a fly by the seat of your pants [operation] in the way that best laid plans never quite come together. They have so many [characters] to take care of and I think once they made the decision that all these characters were going to graduate, it shifted the way this season was going to go."

Murphy, who was speaking to Socialite Life at a preview screening of the second season at the Leonard H. Goldenson Theatre in North Hollywood last night, revealed that fans can expect to see the Maroon 5 frontman in a different light.

He said: 'He’s a sexy guy, so he needs to play a sexy guy, but a guy that is different than who you think he would play.

“The second season is fun, sexy and baroque. It has a lot of meat to it. It’s a really gritty part. He's with a girl and they play characters called The Lovers."

Murphy, who is also responsible for the likes of Glee and Nip/Tuck, said the 'Moves Like Jagger' star didn’t take much persuading to take the role:

“I pitched him the part and he listened slack jawed and simply said, ‘I’m in.’” 

The 'Your Song' superstar has previously expressed his love for the musical drama series and said that he would love a starring role if the opportunity arose: "I haven't been asked to go on Glee but I love the show, it's such a positive show and I enjoyed doing the Matthew Morrison duet very much."

Murphy has also spoken out in the past about how great it would be to get Sir Elton involved, but the timing hasn't been right this time around as the icon's tour schedule clashes with filming and Murphy told TV Guide:

"I'm currently meeting and talking to (actors). So many people are interested in playing them, but (Elton) is, unfortunately, touring."

It was announced back in July that Overstreet, who plays ladies' favourite Sam Evans on the hit musical series, wouldn't come back for season three as a regular cast member but Murphy has now decided to write him back in as a full time character. He told US Weekly in an official statement:

"We love Chord and have always said that we wanted him back."

"So here's an early Christmas present for all the Gleeks - Sam is coming back to McKinley, and just in time for sectionals!"

The Foo Fighters frontman appeared as a guest on Chelsea Lately (Wednesday, September 7) and revealed that he didn't realise who he was giving the original interview to so didn't think to edit his word choice accordingly:

"I was doing an interview with the Hollywood Reporter, I didn't realize it was some TV hollywood thing, I was talking to some dude and I said f*ck 'Glee.' Why should you have to do it?" he said. "Why is that necessary for you to have to do, as a rock musician, why should you have to say okay glee, take my song and turn it into a fucking musical."

"As a musician, you should be able to say no, should be able to say I don't want to do your show, you should be able to say I dont want to do anything that someone tells me to do", he added.

Speaking to a packed audience at the event, Brad Falchuk explained that just because the stars are graduating from the fictional high school it doesn't mean that they're leaving the hit series:

"Here's the exact thing: [Rachel, Kurt and Finn] are seniors so they're graduating, but because they're graduating doesn't mean they're leaving the show. If you have Lea Michele under contract, you don't just say, 'We're gonna let you go.'"
