Rihanna also changed for her performance at the 2011 Grammy Awards.

She opted for a very dramatic Christian Dior Fall 2010 Couture gown whilst performing with Eminem.

The breath-taking black gown has a yellow petal print underskirt which has a rise and fall hemline.

I prefer the heels on the runway, but this is an amazing look from Rihanna.

She really knows how to work Couture both on the runway and on the stage.
