The 'Deadpool' star - whose wife gave birth to their first child in December - was amazed by how much he loves his little girl and wanted to protect her as soon as he saw her.

He said: "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."

Though his little girl comes first, the 38-year-old actor admits he is more in love with Blake - who he married in September 2012- than ever.

He gushed to talk show host David Letterman: "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."

Because Blake is breastfeeding the baby - whose name the couple haven't disclosed - the pair's parenting roles are very different, and Ryan joked his life is like a "beautiful" Denny's.

Referring to the family restaurant chain, he said: "[As] the guy, I'm just like a diaper-changing facility hooked up to a life-support system. But my wife, she's breakfast, lunch, and dinner.

"She's a human Denny's, all day long and all night long. Romantic right? She's the most beautiful Denny's you've ever seen, though."
