Justin Bieber and Chris Brown appear to have recorded music together, as the R&B singer promises a "BANGER/SMASH record" around January 2011.
Bieber, a 16-year-old pop star and one of the most popular young artists in the world, has not commented. He is the protégé of R&B singer Usher and has in the past collaborated with him as well as with artists such as Ludacris and Sean Kingston and the band Rascal Flatts.
Brown made headlines in 2009 when he was arrested and convicted of assaulting then-girlfriend Rihanna. He completed a round of court-mandated domestic violence classes earlier this month.
On Feb. 11, 2011, Bieber is set to release a movie about his life called "Never Say Never", which also features Jaden Smith and Miley Cyrus. Bieber has been busy this past year - he made his acting debut on "CSI: Crime Scene Investigation", released two albums and a memoir and inspired a line of nail polish.
