Who wears short shorts? Kristin Cavallari wears short shorts! The former Hills star, 26, showed off her long, lean legs while out and about in L.A. on Wednesday, Feb. 12, less than six months after giving birth to son Camden.

The new mom flaunted her flawless stems in a pair of high-waisted black-and-white zippered shorts, paired with black platform booties and a black sleeveless sweater that exposed just a sliver of her toned midriff. Her blonde hair hung in loose curls past her shoulders.

Cavallari welcomed her first child with fiance Jay Cutler on Aug. 25, 2012 -- and five-and-a-half months later, she's as svelte as ever. The secret to her super-slim post-baby bod? Healthy eating and no alcohol!

"I'm like a freak about eating healthy," she told Us Weekly at the launch of her jewelry capsule collection with Pascal Mouawad for Glamboutique on Feb. 5. "I've always been a really healthy eater. I think when I got pregnant I took it up another notch, just because I was so aware of what I was putting in my body. I've just maintained that since I've had Cam. And honestly, I rarely drink alcohol, which helps too. It's just empty calories."

She makes an exception to the healthy-eating rule for dessert, though. "I have a huge sweet tooth, but I'll get dark chocolate with caramel," she told Us. "Or there's an ice cream at Whole Foods called Coconut Bliss, which is made out of coconut milk, and so, to me, that's not really cheating."
