Kim Kardashian is heading down the aisle very soon, and the reality star wants to make sure her booty is in fine form for her fiance Kris Humphries. Looks good to us, Kim!

The 30-year-old starlet ditched the makeup, but brought along her yellow Hermes bag, while hitting up the gym in Los Angeles. We love how Kim parks her insanely expensive Bentley on the curb. Way to keep it real!
