Hot dad alert!

Ryan Reynolds appeared on The Late Show with David Letterman last night, and the actor was quizzed about baby names and fatherhood by the gap-toothed host.

"We definitely [have a name]. I threw out the idea of just never naming the kid to be totally original, but we have a name. I just don't want to say it in, like, a media context. I tell everyone who I meet, so it'll come out," he joked.

Letterman then threw out random girl names in effort to get the Canadian hunk to reveal his little princess' moniker, but he didn't take the bait. "I should've worn my cup. I didn't know I was gonna get busted this hard!" Blake Lively's husband quipped.

The Proposal star was slightly more forthcoming when asked about expanding his family and his relationship with his A-list actress wife. "It's amazing. I'm not one for vomiting declarations of sentiment out across the airwaves, 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," he gushed. Awww!

After welcoming a child, though, the Gossip Girl star is a little lower on his totem pole of responsibility. "I used to say to [Blake], 'I would take a bullet for you. I could never love anything as much as I love you.' I would say that to my wife. And the second I looked in that baby's eyes, I knew in that exact moment that if we were ever under attack, I would use my wife as a human shield to protect that baby," he kidded.

Fatherhood looks good on this jokester!
