Peyton and The Bachelorette's Season 6 runner-up reportedly named their son Hayes Jennings, and he joins the couple's two-year-old daughter Lyla.

"Lyla James is in love with her baby brother," Peyton and Chris told Us. "It's adorable."

Peyton, 35, announced in a July blog post that she and Chris were expanding their family with another baby.
Although Chris -- whose Lawn & Order series premiered in May on DIY Network -- and Peyton underwent in vitro fertilization to conceive Lyla, the couple had a little miracle with Peyton's second pregnancy, as they conceived naturally.

"We went through so much to bring [Lyla] into this world, I just assumed [in vitro] was how we would create all of our babies... boy was I wrong," Peyton wrote in her blog at the time she revealed she was expecting.

"It's funny how things work out. In April we went to visit our IVF clinic to find out the process for transferring one of our frozen embryos. We were lucky to have 3 frozen from my first retrieval in 2016... I thought maybe we would schedule to implant... after the summer was winding down," she continued.

Peyton said her second pregnancy was "a complete shock" and she found the experience to be "exhilarating."

Peyton competed for Andy Baldwin's heart on The Bachelor in 2007. As for Chris, he vied for the affection of Ali Fedotowsky on The Bachelorette in 2010.

Chris and Peyton were introduced by mutual friends after their respective seasons of ABC's reality dating competition, and they married in 2012. The pair welcomed Lyla in November 2016.

In addition to their Bachelor-franchise shows, Chris and Peyton have starred on the HGTV series Going Yard as well as the DIY Network series Yard Crashers.
