Brittany Matthews Says 2021 'Brought Me My Biggest Blessing' with Birth of Daughter Sterling Matthews and Mahomes, 26, recently celebrated their first Christmas with their daughter. After the holiday, the NFL star opened up about the "awesome" experience in an interview with The Drive on 610 Sports Radio. "It worked out well for us, and we had a home game that Saturday," Mahomes said. "We had that morning to be with the kids, and do all the gifts and everything. Sterling, I don't think she understood what Christmas was yet, but she understood she got a lot of toys." One of their daughter's gifts from her parents included a mini Lamborghini, he shared. "It was awesome, and you can control it through a little remote control, too," Mahomes said. "I think it's a bad sign for me that she's already getting a black Lamborghini. Brittany's already putting it in her head." He added, "She was playing with literally everything. It was fun to see her do that."
