The purple-haired pop princess wore a crystal-embellished frock. Shine on, girl.

Still riding her post-Super Bowl performance high, Katy Perry shined on the red carpet at Sunday's Grammys. The pop princess wore an outfit fresh off the Paris Couture runway: a crystal-embellished, sheer dress by Zuhair Murad.

Perry, who complemented her purple hair with blue Cover Girl mascara, told Ryan Seacrest that she "wanted to shine bright like a diamond." Mission accomplished.
