The American Music Awards took place last night and the evening was definitely one to remember. From Rihanna’s intriguing performance of Rehab to Leona Lewis’ soulful rendition of Better in Time, the music industry had a lot to celebrate during last night’s event.

And while several of the music industry’s finest singers were on hand to accept their awards, it was the unbelievably sexy fashion choices that kept viewers on the edge of their seats.
