Katy Perry is one of the most beautiful women in the pop world but at Sunday's Teen Choice Awards, Katy donned some geeky looking attire, including a head brace and oversized spectacles.

We're loving Katy's confidence to dress down but by the looks of her fiance, Russell Brand's face in this picture. He wasn't quite so keen on his wife-to-be's new look.

Russell posted a photo of him and Katy in her geeky gear on his Twitter account and wrote: "The real winner of the Teen Choice awards is... I AM! I won a fantastic new bride"

We think Russell's done well for himself! Are you a fan of the California Gurls star?

Katy's not afraid to look silly...
