Nothing can keep Patrick Mahomes and Brittany Mahomes' kids' spirits down on Christmas Eve - even a treadmill mishap with mom. "Christmas Eve workout with my kiddos," Brittany, 30, captioned an Instagram Story video of her and Patrick's eldest children, Sterling, 4, and Bronze, 3, walking on the treadmill next to her on Wednesday, December 24. (The couple also share daughter Golden, 11 months.) In the video, Brittany has her head down focused on her workout as Bronze and Sterling try to keep up beside her - but they can't hang.
