Rihanna, Drake Deliver Sexually-Charged 2011 Grammy Performance

Rihanna and Drake offered a sexually-charged performance of their No. 1 hit 'What's My Name' on tonight's 2011 Grammy Awards.
The rapper and R&B star grinded together during the early part of the song. Drake delivered his innuendo laden verse including lyrics about the "square root of 69," while Rihanna gyrated behind him.

Drake exited early, allowing Rihanna to take center stage. Midway through, the song took on a more tribal feel with the addition of bongo drums and a group of exotic-looking dancers behind the young superstar.

For Rihanna, the performance was her second of the night, as she joined Eminem earlier for 'Love the Way You Lie.' Not bad for someone whose Grammy status was in doubt after she reportedly fell ill in recent days.
