EXCLUSIVE PHOTOS - Kim Kardashian Tones Her Tush At Pilates Class

These workouts are really paying off!

Kim Kardashian woke up bright and early to take a pilates class in L.A., and the reality star seems to be keenly aware that she better keep her booty tight and toned since it's landing her in the headlines lately!

The Keeping Up with the Kardashians star caused a frenzy yesterday when photos of her massive derriere, which were taken during her Thai vacation, surfaced online, and today her fiancé Kanye West's collaboration with Future on "I Won" was leaked and it's all about Kimmy K's butt!

"I want to dip that ass in gold, I want to dip that ass in gold / I made it over NBA, NFL players / So every time I score it's like the Super Bowl. Baby, we should hit the south of France / So you could run around without them pants," reads some of the lyrics.

If she didn't have that tush, we wonder where she'd be? Probably working at a clothing store in the valley like she was pre-sex tape!
