Mahomes and Matthews set a 2022 wedding date in March but did not reveal their venue or spill specific details about their plans at the time. In a July interview with PEOPLE, Mahomes said he's envisioning a big role for Sterling when he and Matthews tie the knot.

"She'll be, I think, a little over a year old by the time the wedding happens ... so hopefully she'll be able to be the flower girl and be able to be walking by then and do all that cool stuff," he said. "But she'll be a part of the wedding no matter what."

Mahomes previously told PEOPLE becoming a dad to his daughter is "awesome," adding that he feels "blessed to have a really, really good first baby in Sterling."
