Pucker up: Kristin Cavallari plants one on son Camden.

Kristin Cavallari is one busy lady. When she's not co-hosting E!'s "The Fabulist," she's designing shoes for Chinese Laundry and jewelry for GLAMBoutique. Plus, she's also a devoted wife to NFL hubby Jay Cutler and mother to 20-month-old son, Camden. Oh, and she's currently eight-months pregnant with another boy. We need a nap just thinking about it.

Yet nothing seems to slow the beautiful fashionista down. After a long day on set, K-Cav posted the above Instagram pic of her sneaking a smooch with Camden, and it's giving us heart flutters. "Just got done shooting fun stuff for @eonline with @jencooperphoto," the former "Hills" star wrote alongside the photo. "Was so nice to be at home with this little man for hair and makeup."

We officially crown this former Queen Bee the Queen of Working Moms!
