Kristin Cavallari posed as "naughty" while her husband NFL's Jay Cutler posed as "nice" in a Holiday photo shared on Instagram Friday.

The shot was taken at a party in benefit of the The Jay Cutler Foundation, an organization that funds screening clinics to test for childhood diabetes.

"Ugly sweater party to benefit The Jay Cutler Foundation. Thanks to everyone that came! #charity #diabetes #type1," Cavallari wrote on the image's caption.

A second photo from the event found Cavallari goofing around with a friend. "The funny thing is I'm actually sober @sbiegs," she captioned the shot.

Cavallari is best known for her roles in the reality series "Laguna Beach" and "The Hills."

She married the Chicago Bears quarterback in 2013 and they have two children together, Camden Jack, 2, and Jaxon Wyatt, 7 months.
