NFL star Patrick Mahomes and his fiancée Brittany Matthews have been dating since their teen years
Patrick Mahomes and fiancée Brittany Matthews welcomed their first child, daughter Sterling Skye on Saturday, they announced on Instagram. The new parents shared a photo of the newborn's hand holding onto her father's finger.
"Sterling Skye Mahomes 👸🏼 2/20/21 6lbs 11oz," Matthews shared on Instagram.
Mahomes also shared a similar caption, "Sterling Skye Mahomes 2/20/21 ❤️."
The longtime couple began dating in their teens and got engaged in early September, with the quarterback popping the question to the former pro soccer player after the Chiefs' Super Bowl ring ceremony. Later that month, they announced the pregnancy news, adding that they were "taking a small detour to the wedding."

"I'm so happy for you guys and can't wait for all the adventures and happy times," Mahomes' younger brother Jackson shared on his Instagram Story Sunday.
"@patrickmahomes will be the best dad!" Jackson wrote. "@brittanylynne will be the best mom! Love you 3."
The couple found out the sex of their baby on the way in October, both embracing and sharing in excitement about expecting a daughter. Prior to that, when asked on The Drive in September whether he was hoping for a son or daughter, Mahomes said, "I'm just super excited to hopefully have a healthy baby and someone I'll be able to love for the rest of my life."
As for what 2020 taught him on a personal level, Mahomes responded, "I think it's just about growing up, about having the responsibility and evolving as a family."
"I think we've done that — me and Brittany, and the people around me — and I'm just excited for the future ahead of being able to keep building and keep becoming a better person for my family and this world," he added.
The Kansas City Chiefs player said in a December interview with KCSP 610 Sports Radio that the best thing that happened to him this past year was a "tie" between his engagement and the subsequent news that they were expecting.
"Those things are special, that you don't get to happen a lot in your life," he said at the time. "Being able to be a dad and being able to get married here soon, I'm truly thankful for that."
"I mean, [winning] the Super Bowl was awesome as well," Mahomes added, "but those things change your life, and it's bigger than football."
Mahomes also said his primary objective for 2021 is all about being the "best father I could possibly be" to his baby girl: "This will be a new thing for me, first-time dad. Being able to experience that and go through that, I want to do whatever I can to make our little girl's life as best as it can possibly be."
