"Spencer is going to bring a lot of strength. I think that he's very loving. He's very loyal. He has a great heart. He's very genuine. He's smart. He's got a great heart," the reality star said. "Spencer's going to be a really great model. He's going to be very active in our son's life."
Montag noted that while Pratt wanted a girl, the couple is thrilled to be welcoming a son into their family and Pratt is looking forward to playing sports and doing activities with their son.
"I thought he'd be more excited to have the boy," she explained. "He said, 'But I did want a little Heidi.' "
Montag added that she wants to be "the ultimate mom" to their child, and has even gotten some tips on motherhood from former The Hills co-stars Audrina Patridge and Kristin Cavallari, although there are other co-stars she hasn't heard from.
"Not Whitney [Port], surprisingly," Montag said. "But I guess we're not really friends anyway. And obviously, not Lauren [Conrad]."
