Kim Kardashian, Molly Sims gym Studio City blonde bruenete tights leggings

Kim Kardashian is so glam, she totes her $15K Birkin to the gym and doesn't think twice. And since the Birkin comes with a years' long waiting list (unless you're Kim K) we can't fathom throwing it in the bottom of a dirty locker!

Kardashian has been hitting the gym a lot lately, but the sexy reality star says she still has "cellulite" and "jiggly thighs," even though she works out seven days a week.

Kim opened up to April's Self magazine, revealing: "Of course I struggle with insecure moments ... And I'll say it. I think my thighs are jiggly and I have cellulite."

We don't hear the guys complaining!
