The Staples Center will get to hear Katy Perry roar.
The singer will perform at the 56th Grammy Awards, the academy revealed today. Other just-announced performers include new pop royal Lorde, eight-time Grammy-winners Metallica with Grammy Cultural Ambassador to China Lang Lang; Nile Rodgers, and Pharrell Williams.
Of course, one of the most exciting parts of the Grammys in the unexpected performance duos. This year, 25-time Grammy winner Stevie Wonder will join a previously announced performance by nominees Daft Punk; and Robin Thicke will join classic rockers Chicago, who will presumably not twerk on Thicke in any capacity.
Previously announced performers include Pink and Kendrick Lamar. The Grammys, hosted by LL Cool J, take place Sunday, Jan. 26 at 8 p.m., and will air on CBS.
