Peyton previously vied for the heart of Andy Baldwin on season 10 of The Bachelor, while Chris was a runner up on Ali Fedotowsky's season of The Bachelorette. The couple married in 2012 after meeting through mutual friends at a Bachelor event, and announced they were expecting their first child in June.
"We are thrilled!" they said at the time in a statement to ET, revealing that they weren't going to find out the gender of their new baby until the big day.
"If it were up to me, I would find out because I'm a planner," Peyton explained. "But it was important to him, so I agreed."
Chris and Peyton aren't the only Bachelor alums to welcome babies this year. In fact, Chris' ex, Fedotowsky, welcomed her own bundle of joy, a daughter named Molly, in July.
