Three weeks ago, the blonde beauty, 32, showed off a hint of a baby bump while posing with Buffalo Bills player Aaron Williams.

Chad and Sarah, who secretly tied the knot in January 2015, are already parents to a 17-month-old son, whose name has never been released. They originally met on the short-lived TV series Chosen.

The One Tree Hill alum previously opened up about becoming a parent, telling ET in July, "Having a family just changes your perspective on everything. I mean, it's a world changer… For me, it was the greatest thing that's ever happened to me."

Congrats to the happy couple!
