The Grammys have caught a serious case of Bieber Fever.
Best New Artist nominee Justin Bieber has been added to the growing list of performers for this year’s awards show. He confirmed rumors of a performance today (January 19) on his Twitter account and revealed another performer in the process (we assume). “Excited for the #grammys – officially performing and bringing my big bro [Usher] with me. super grateful. the GRAMMYS!!,” Bieber tweeted.
The Grammy news continues to leak out. StereoGum.com reveals rockers Muse are also on tap to perform. Earlier today, Rolling Stone announced Bruno Mars, B.o.B, and Janelle Monae as performers.

The new batch of announced performers will join previously confirmed acts Eminem, Lady Gaga, Katy Perry, Cee-Lo Green, Arcade Fire, and Miranda Lambert.
At this point, there is still no confirmation on the rumored Britney Spears performance, though more performers and presenters are still yet to be announced.
The 53rd annual Grammy Awards will air live Sunday, February 13 at 8pm EST on CBS.
