Rita Ora performs David Bowie's 'Fashion' at Fashion Rocks...

Was last night Fashion Rocks, or Ass Rocks instead? I'm actually glad I didn't stay up to watch this. It just seems like everyone was competing with each other for the most ass exposure. With both Jennifer Lopez and Nicki Minaj putting it all out there, I guess Rita Ora felt a little left out.

Here, she delivers a couture-studded performance of 'Fashion.' Check it out inside.

Thoughts?
