She just had a baby!? Kristin Cavallari stuns in sexy black dress

She’s bounced back! Kristin Cavallari made her first appearance on the red carpet since giving birth to Camden two months (yes, just two months!) ago. The reality star wore a sexy black dress at the ULTA Beauty: Donate With A Kiss Launch at The Jimmy at the James Hotel. Hmmm… think she has on a pair of Spanx under that dress?

How did the 25-year-old lose the baby weight so fast? A source told Us Weekly she has been “working out like crazy with a trainer” since giving birth to baby Camden.
