Sure, the GRAMMY Awards red carpet will be chock-full of show-stopping looks on February 13, 2011.

We’ve come to expect that.

But with the announcement of more performers today, there’s a pretty good chance we’ll also be yakking about stage outfits when the curtains close on music’s biggest night.

On Wednesday, the Recording Academy confirmed that Rihanna will perform with Drake on live television for the first time ever. She joins a list of other style shakers Sooo Fabulous! will be eying during the night: Janelle Monáe, Gwyneth Paltrow, Lady Gaga and Katy Perry.

The GRAMMY Awards broadcast airs live from the Staples Center on the CBS Television Network from 8 – 11.30 p.m. ET/PT.

Meanwhile, take a fun look back at last year’s looks.
