The Canadian star and his manager Scooter Braun expressed their disappointment last year after the 'Believe' star missed out on nominations for the 2013 Grammys, which took place on Sunday (February 10).

The Black Keys won a total of four gongs on the night and they managed to find time to slate Bieber, with drummer Patrick Carney joking:

"He's rich, right? Grammys are for like music, not for money...and he's making a lot of money. He should be happy."

This seems to have not sat well with Bieber, took tweeted today (February 12):

"The black keys drummer should be slapped around haha."

The music star posted the track 'You Want Me' last night (February 10) on Soundcloud, with Bieber claiming it is "part" of a song.

He said: "It's not finished but heres a little part a song I'm working on."

The song's release comes soon after the singer released a collection of stripped-back tracks in the form of 'Believe Acoustic'.

Some Twitter users, however, believe Bieber uploaded the track last night to deter attention away from the Grammy Awards.

The singer wasn't nominated for any gongs at this year's ceremony and his manager Scooter Braun had previously hit out at their team for snubbing his client.

The star made his hotly-anticipated debut on the hit US comedy show last night (February 9) where he made light of rumours surrounding his personal life.

Earlier this year, Bieber was pictured holding a suspicious looking cigarette - leading many people to speculate whether or not he was smoking marijuana at a party.

The 18-year-old star played the ultimate Miley Cyrus fan in a later skit during his appearance on SNL.

During the hilarious sketch, the character proclaimed her hatred for Justin Bieber.

The heartthrob's tongue-in-cheek character chimed: "I also heard he got busted smoking weed, and people make mistakes and he’s really sorry about it and he’s never going to do it again.”

Earlier in the show, Bieber was joined by Whoopi Goldberg and Ellen DeGeneres.

18-year-old Bieber's hugely successful 2011 3D concert film 'Never Say Never' was a box office hit and documented his rise to fame from an early age. The film also showed footage of his 2010 concert tour.

The star's manager Scooter Braun has now revealed Bieber is committed to sharing all of his live show experiences with fans from across the globe.

Braun told MTV News: "What we want to do is ... the concerts sell out so quickly, which has really been a blessing. But Justin and I were talking about how there's so many kids out there who are in a position like he was growing up who don't have a lot of money, who aren't able to go to concerts.

He added: "He wants to put each one of his tours for the rest of his career in theatres for at least one weekend so that kid can to the theatre, pay their $10 and have that experience."

Braun revealed that the "movies" won't be in a documentary-style format as 'Never Say Never' was, continuing: "This is more about just giving them the concert and letting all the kids around the world for one weekend go to the concert together and then go back home and go online and share their experience."

Bieber is currently busy with rehearsals for his 'Believe' tour, taking to Twitter this week to share his hard work with fans.

He wrote: "Rehearsal rehearsal rehearsal .... Rehearsal. up real early today for a LONG DAY of rehearsals. and now a blizzard is coming. no issue. Im Canadian (sic)."

Despite having an incredibly successful year, Bieber hasn't been nominated for any titles at the 2013 GRAMMYs and Mallette explained that she's not only really disappointed, but surprised at the organisation for not recognising his talent:

"I think they blew it. It's my boy, I'm a little biased. I just heard that he's had now five No.1 albums, so I think his music is speaking for itself."

When asked how the 'As Long As You Love Me' hitmaker had taken the news, she admitted that it's giving him something to work towards for the next ceremony: "I think it's kind of good in a way. It gives him something to strive for and a goal to go for."

The 2013 GRAMMYs will take place this coming Sunday on February 10 in Los Angeles.

Watch Mallette talk about Bieber's relationship with Gomez here:

Eyebrows were raised recently when the singer-songwriter revealed on Twitter that he was in the studio with Bieber's manager Scooter Braun.

The 'Boyfriend' man tweeted at the same time that he was working in a studio too, causing people to put two and two together.

However, Sheeran told The Sun that he actually wrote a song with one of Braun's other clients, believed to be Tori Kelly. He said:

"I met Bieber’s manager Scooter Braun in New York and he said he’s got this artist I want you to write with. Next time I was in LA, I was doing Jimmy Kimmel and he brought this girl to Kimmel and I met her straight afterwards. I then went to the studio and did a song."

Sheeran added:"I don't think a collaboration would work with Justin. I think collaborations should be done with people that can actually click. Two male singers makes it very difficult for it to work."

While Mallette has previously spoken out in favour of the 'Like A Love Song' beauty, telling Ellen DeGeneres that "she’s good for him and they’re great together”, during a new interview on 'Today' in the U.S. she explained that she supports his decisions regarding his love life:

"You know, I just try and support whatever he's wanting," she confessed, without giving anything away.

"I think [Selena is] a sweetheart, and whatever they decide is great."

Meanwhile, Bieber recently made music history by becoming the youngest artist to have achieved 5 No.1 charting albums with the release of his latest offering, 'Believe Acoustic'.

Tweeting about his continued success earlier today (February 7), the 'Boyfriend' singer wrote: "If u wanna succeed u gotta put in the work."

Check out Bieber's brand new SNL promo below:

Yesterday (February 6), the Canadian became the first artist to achieve five No.1 albums in America before the age of 19.

He was previously tied with Miley Cyrus, who has had four No.1 albums before turning 19.

The record was created after his new album 'Believe Acoustic' topped the Billboard charts after selling 211,000 copies.

Taking to Twitter as he heard the news, Bieber said: "GREAT DAY".

The 'Boyfriend' star meanwhile is only one of ten artists in history to have four No.1 albums in four consecutive years in the US.

Bieber meanwhile is due to host and perform on iconic TV show Saturday Night Live this weekend (February 9).

After sitting down for an interview with the well-loved TV host, during which he showed off his enviable abs, Bieber was then invited to play a game where he had to throw objects through a basketball hoop.

One of the items he was asked to launch into the hoop was the head of a mannequin and Bieber took it in both hands and began making out to it, which sent the audience wild and caused them all to whoop and scream.

Fallon caught sight of the kiss and yelled out: "Hey, whoa whoa whoa! Don't fall in love! Don't fall in love! Justin, don't fall in love with her. Justin, hey, Justin!"

The clip has since been uploaded to video hosting site YouTube and it has attracted many comments based on the superstar's kissing technique, with one user writing: "That moment when you are jealous of a mannequin..."

Another added excitedly: "Holy sh*t. he looks a f**king amazing kisser."

Watch the tender moment unfold below:

The singer found fame after being discovered on YouTube as a young teenager in 2008 by manager Scooter Braun.

Speaking on the Jimmy Fallon show, Bieber said his tunes reveal that he is an "artist" - not a "made" pop product. He said:

"It's just good music. It just shows that I wasn't made, I was found on YouTube and it shows people music is music. That's what you need to focus on - listening to the music. I'm an artist. I want to show people what I love to do."

The 'Boyfriend' star added that his new album 'Believe Acoustic' highlights his YouTube roots, explaining:

"I wanted to basically strip it down so it's just me and an acoustic guitar. Some of it is me and a piano but most of it is just raw me. I think the fans really like it because it's just kind of how I started. I started with just me on the internet. Not really with all the produced pop music and so it's just that it's just really mellowed down and I feel like it's made for all ages."

Bieber meanwhile also took to kissing a mannequin whilst on the show - promptly sending Twitter wild as a result.
