Kristin Cavallari shares slim post-baby selfie

LOS ANGELES, Dec. 3 (UPI) -- Kristin Cavallari took to Instagram to share a post-workout selfie Sunday.

The 27-year-old television personality looked incredibly slim and fit just seven months after giving birth to her second child. Cavallari and husband Jay Cutler are already parents to two-year-old son Camden Jack, and welcomed son Jaxon Wyatt in May.

"Just got a nice little workout in. Yes, those are baby monitors behind me. #GottaLoveNapTime," she captioned the photo.

Cavallari recently spoke to Access Hollywood and admitted she worked hard to drop the baby weight. She was able to lose 20 pounds in just two months, and explained, "You have to eat really well and workout."

Cavallari came to fame on MTV reality series Laguna Beach, and later appeared on fifth and sixth seasons of The Hills. She and Cutler have been married since June 2013, and the television personality revealed Jaxon struggles with colic in October.
