After David Letterman hilariously put Ryan Reynolds in the hot seat by trying to guess baby names, things took a supersweet turn as Ryan started talking about his relationship with his wife, Blake Lively. "I'm not one for, you know, vomiting declarations of sentiment out across the airwaves," he said on Wednesday's episode of Late Show with David Letterman. "But when we had that baby, I fell more in love with my wife than I'd ever been in my entire life. I couldn't even believe it." Ryan said that in the past, he'd always tell Blake that he'd take a bullet for her because he loved her so much, adding that things have changed since becoming a dad. He joked, "I would use my wife as a human shield to protect that baby."
