"We are thrilled!" the couple announced in an exclusive statement to ET.
"I'm into my second trimester now and due in November," Peyton revealed.
The HGTV host, who previously vied for the heart of Andy Baldwin on the tenth season of The Bachelor, tied the knot with Chris in 2012 after meeting through mutual friends at a Bachelor event.
Peyton told ET that she's been doing better after a physically challenging start to her pregnancy. "I was pretty sick during the first trimester but feeling much better now," she shared. "Finally have some energy back which is wonderful!"
The expectant mom
also revealed that the couple isn't going to find out the gender of their forthcoming bundle of joy ahead of time, which she says was entirely Chris' decision.
"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."
Congrats to the happy couple!
