Kristin Cavallari uploaded a photo on Instagram on Sunday, in which she wore no makeup.

"Go Bears #nofilter #nomakeup #dontcare," the 26-year-old captioned the shot.

This isn't the first time, however, that the former Hills star showed off her bare face. Cavallari has posted photos of herself with little to no makeup several times before proving that her natural look is stunning.

The 26-year-old also got right back into shape after she gave birth to her first child, Camden, in 2012. She spoke to EnStars at the Junk Food Vintage NFL runway show in September and said that her son has started calling her "mom." She also revealed that she and husband Jay Cutler are planning to have another baby one day.

"He is trying really hard to talk, so it'll only be a matter of time until he starts saying more words," she said. "He is moving all over the place and won't sit still. It's a blast. His little personality develops more and more each day. He is the best little boy in the world."
