Reality star Kristin Cavallari apparently made Santa Claus's list this year, but was she on the naughty or nice list?

Kristin Cavallari Felt 'Gross' During Her Pregnancy?

The Hills star took to Instagram on Friday where she posted a snapshot of herself with her husband, Jay Cutler, as they embraced the holiday season in green and white sweaters. Cutler held a stick with a Santa hat over his head as well as a sign that said 'Naughty.' Cavallari had a stick with a Santa beard along with a sign that said 'Nice.'

This photo was for a good cause where she mentioned in the caption how glad she was to be a part of it.

"Ugly sweater party to benefit The Jay Cutler Foundation. Thanks to everyone that came! #charity #diabetes #type1," she wrote.

Cavallari and Cutler got married in June 2013. They have two kids together, Camden, 2, and Jaxen, seven months.

In a recent interview with Access Hollywood, the reality star pointed out how she's been keeping herself in shape after having two children.

"I've been working out really hard. Those last five pounds are really stubborn. It's in your stomach," she said. "You have to eat really well and work out."

Cavallari also dished on how she balances her diet out.

"I don't put any toxic chemicals in my body," she explained. "I'm a freak about reading the ingredients. I don't count calories, I just read what's in whatever I'm going to be putting in my mouth."
