Kristin Cavallari -- Check Out My Hot Post-Pregnancy Ass

It's only been 10 months since Kristin Cavallari popped out her kid ... and she's already snapped back into bikini shape.

The 26-year-old former MTV star -- who's engaged to perennially injured Chicago Bears QB Jay Cutler -- gave birth to their son Camden Jack last August.

Cutler missed most of the 2011 NFL season with multiple injuries. Hopefully, KC can teach him a few things about returning to form.
