Chris Lambton and Peyton Lambton have welcomed their first child.

"The Bachelorette" Season 6 runner-up announced Tuesday on Instagram that Peyton, a former "The Bachelor" Season 10 contestant, gave birth to daughter Lyla James.

"Happy to announce the addition to our family Lyla James. Baby and mom are both doing great! #BabyLambton @peytonwlambton #imadad," he captioned a photo of himself with his family.

"I never knew I could be so in love! Lyla James is here and our life has changed for the better!! #babylambton #itsagirl #soinlovewithher," Peyton added to a later post.

Chris and Peyton were introduced by mutual friends after their respective seasons of "The Bachelorette" and "The Bachelor," and married in 2012.

The couple revealed in June that they were expecting.

"Our families are over the moon that we are finally joining the parent club," Peyton told E! News at the time. "I'm an only child so this will be the first grandchild for my parents, and they are thrilled."

"We're thrilled to be expecting," she added to People. "It's something we've wanted for a long time, and we're so excited it's finally here."
