Crazy Grammys Fashion!
Check out the wildest Grammys fashion.
Katy Perry went from angel to sparkly swing girl when she performed at the 2011 Grammy Awards on Sunday night.

The stunning pop star – who walked the red carpet with a huge pair of white angel wings – sat on a swing in a bejeweled leotard and tutu while footage from her wedding to Russell Brand played in the background.

After she was done singing her ballad, Katy got down from her swing and kicked things up a notch for a powerful performance of her hit, “Teenage Dream.” At one point, Katy told the audience to sing the words with her and Nicole Kidman began to sing along in the audience. We didn’t know Nicole was a Katy fan!
