Later that same month, the pair announced their pregnancy news, adding that they were "taking a small detour to the wedding." Announcing the birth of their first baby, the new parents shared a photo of the newborn's hand holding onto her father's finger earlier this year. "Sterling Skye Mahomes 👸🏼 2/20/21 6lbs 11oz," Matthews wrote on Instagram as Mahomes also shared a similar caption, writing, "Sterling Skye Mahomes 2/20/21 ❤️." Mahomes recently told PEOPLE that becoming a first-time father has been "awesome" and he is "blessed to have a really, really good first baby in Sterling." "Brittany has helped out a ton being a champion mom, and so it's been a lot of fun and to be able to come home every single day and see her and how energized she is and how she's changing and growing already," he added. "I'm just trying to tell her to slow down so I can enjoy every minute of it."

"I've grown a lot in my first few years in the NFL, and I've had to take on a lot of responsibility, but nothing's like having a kid and having someone that you're going every single day knowing that you're trying to take care of," he said. "And to have her and Brittany and my family, I mean, it truly is an amazing feeling," Mahomes continued. "To know I get to go to work every single day for something and then get to come home and enjoy the time I get with them."
