Justin Bieber has reportedly recorded with Ke$ha for his third studio album Believe, which is due later this year.
Not content with already having secured Drake, Lil Wayne, Chris Brown, Timbaland and Pharell Williams, the teen icon has now been linked to the 'Tik Tok' hitmaker, who has written the tune after the critical success of 'Till The World Ends', the track she penned for Britney Spears.
A source told Hollywood Life that the blonde star, whose second album is due in 2012, "would also be a part of the song in a duet capacity".
She has told reporters of her next record that she wants to make "c*ck rock" music, telling MTV: "I just want to capture some of the true essence of what rock and roll is, and that's just irreverence and sexiness and fun and not giving a f**k."
Bieber, meanwhile, has been keeping his millions of fans updated on Believe's progress via Twitter.
