Congratulations! Bachelor Nation stars Chris and Peyton Lambton welcomed their first child, a baby girl named Lyla James, on Saturday, November 19.

"The amount of love and joy we have for this little girl is beyond anything I ever imagined," Peyton, 33, tells Us Weekly. "She has completely changed our world and I can't wait to raise her to be a strong, independent woman who can be whatever she dreams."

Chris, 39, shared an adorable black-and-white Instagram photo of the family of three on Tuesday, November 22, writing, "Happy to announce the addition to our family Lyla James. Baby and mom are both doing great! #BabyLambton @peytonwlambton #imadad."

Peyton then shared a sweet picture of Lyla on her Instagram account, writing, "I never knew I could be so in love. Lyla James is here and our life has changed for the better!! #babylambton #itsagirl #soinlovewithher."

The happy couple tied the knot in May 2012 at Wild Dunes Resort in Charleston, South Carolina, after being introduced by fellow Bachelorette alum Jesse Beck while at a charity event. They announced they were expecting their first bundle of joy earlier this year.

"We are thrilled to finally expand our family, and we can't wait for this new adventure to begin," Peyton told Us Weekly in June.

In May 2013, the blogger explained to fans why she wanted to wait to get pregnant. "Expanding our family will be a huge decision and we need to be ready to commit to the fact that our lifestyle will change," she wrote on her blog, The Life of Pey. "I think everyone is aware of my only-child syndrome and I am still getting used to sharing a bed with another person! I'm learning to share and I'm still learning that I don't always get on my way. So with that said ... I'm throwing any sort of planning out the window."

Peyton competed for Andy Baldwin's heart on season 10 of The Bachelor in 2007, while Chris, who is a landscaper, was the runner-up on Ali Fedotowsky's season 6 of The Bachelorette in 2010.
