There's another celebrity baby on the way -- Kansas City Chiefs quarterback Patrick Mahomes and his fiancee Brittany Matthews announced they are expecting their first child.

The couple, who have been dating since high school, shared their baby news with the world on Tuesday via Instagram posts.

Alongside a snapshot of Matthews, 25, holding a picture of the sonogram with Mahomes hugging her from behind, she wrote, "Mom & Dad, taking a small detour to the wedding," followed by a red heart emoji.
