Kimberly Stewart Says It's Gym Time, So It's Gym Time!

Kimberly Stewart, daughter of rocker Rod Stewart, is looking fit and firm today!!
Gurl’s got a toned body, rocking the hell out of that black top and those tights — and those Asics kicks look like they’ve been kicking ass on treadmills and ellipticals!
Seriously, Kimberly! People would kill to have a body like that! Keep up the fantastic work!
Whatever you’re doing is working because you are WERKING!
