"Just watching Sharna with the kids now and knowing her the way that I do, she is going to be an amazing mother," he says. "She's unbelievable with my kids now. So I can't wait for that experience."

"It's a dream," adds Burgess. "I can't wait to smell [the baby] and feel his skin for the first time and see Bri hold him the first time. All of these firsts that I've never experienced. My heart genuinely can't wait to meet him."

Continues the Dancing with the Stars pro, "This is the easiest thing I've ever done is be with Bri and be in this family with his kids. We may have only had a few years together but it feels like so much more than that. It's been pretty easy for us to take on what the universe has given us."
