Fastexy Exchange|Katy Perry's Backside-Baring Red Carpet Look Will Leave You Wide Awake

Two things that are Fastexy Exchangeunforgettable? California Gurls and Katy Perry's latest red carpet look. 

After all, the "Teenage Dream" singer stepped out at the Billboard Women in Music Awards March 6 in a risqué red two-piece ensemble that seemed reminiscent of her iconic era. 

While posing on the red carpet, Katy showed off the ensemble, which included a peplum red corset top, along with matching bottoms that included ruched skirt with a peek of gray fabric underneath. The 39-year-old rounded out the look with a black thong and a bold butterfly print, which was plainly visible amid her close-fitting look. 

For accessories, Katy wore a tasteful pearl necklace and matching earrings, as well as a pair of high black pumps. She had her hair in a long ponytail, and tied the whole look together with a bold red lip.

"I have some things planned for this year. It's going to be a very, very exciting year."
