Chris Brown is ready to return to the Grammy Awards.

Unnamed sources told The Associated Press that the singer will be one of the many performers taking the stage at Sunday's show. This will be Brown's first appearance at the Grammys since his 2009 assault on then-girlfriend Rihanna during Grammy weekend. That year both stars were scheduled to perform, but both canceled. Rihanna, however, has since appeared on the show.

Despite being nominated in years since, Brown has not attended the ceremony. The performance is not meant to be formally announced prior to the show.

Brown is up for three Grammys, including Best R&B Album for his 2011 opus, F.A.M.E., as well as Best Rap Performance and Best Rap Song for his track "Look at Me Now," which also features Lil Wayne and Busta Rhymes.

She's set to take the stage with Coldplay and is up for a handful of her own awards including Album of the Year and Best Pop Vocal Album for Loud as well Best Rap/Sung Collaboration for "What's My Name?" which features Drake.

[article id="1677524"]Rihanna and Brown[/article] have recently denied rumors that they are romantically involved. However, the twosome was spotted at the same Super Bowl party over the weekend in Los Angeles, though reportedly they didn't cross paths.

Rihanna and Brown won't be the only two A-listers taking the stage at Sunday's show. Adele, Katy Perry, Taylor Swift, Paul McCartney, Foo Fighters, Bruno Mars, Kelly Clarkson, Jason Aldean and Nicki Minaj are also confirmed to perform live at the 54th annual awards show, which will be hosted by LL Cool J and take place in Los Angeles.
