Kristin stripped her face of slap and donned an official Chicago Bears baseball cap before cheering her hubby on from the comfort of her own home.
The former Hills star then took a selfie before sharing it with her thousands of followers on Instagram, adding that she "didn't care" about her lack of make-up.
Alongside the picture, Kristin commented: "Go Bears #nofilter #nomakeup #dontcare."
