Rumours are rife of a collaboration between the two for Bieber's upcoming Christmas album after one of the superstar teen's backing dancers, Matt Carter, “accidentally” let slip the pair had been in the studio together.
Carter tweeted: “RT @justinbieber @mariahcarey HONOURED. Had to tweet that cause apparently people didnt believe me. haha justin bieber featuring mariah carey. believe it.”
Bieber's people have yet to comment on the rumour, but it seems likely Mariah will be joining Usher, Busta Rhymes and Boyz II Men on The Bieb's 'Under the Mistletoe' LP, released November 1.
Yesterday (Oct 3) we told you how Justin was being urged to boycott Peru over fears for his safety.
