The official twitter account of the Grammy Awards anounced late Tuesday night that R&B superstar Rihanna will perform a duet with Candian rapper Drake at this year's ceremony, wich takes place February 13th. No word on what song the duo will perform, but it could very well be "What's My Name?", the song the two did for Rihanna's "Loud" album. The two stars will join an already star-studded lineup, including Lady Gaga, Eminem, Katy Perry, Justin Bieber, Usher, Muse, and many more. Another big announcement is expected from Grammy organizers Wednesday morning.
