John Stamos says he’s ‘dreaming’ about his first baby: ‘I’ve waited my whole life’ (exclusive)

John Stamos can’t wait to be a dad! The 54-year-old Fuller House star opened up about preparing to welcome his first child to ET’s Keltie Knight at the premiere of his longtime pal Bob Saget’s movie Benjamin on Wednesday.

“I've waited my whole life for this,” Stamos dished to ET. “I just can’t. I'm already so emotional and so excited... I've been dreaming about our baby. I mean, I am really excited.”

After a lengthy career, Stamos sees his new family as the next step.

“I don’t know what I would do if I wasn't having a baby right now,” he said. “Like, I've done everything anyone could ever... I've had the most beautiful blessed life on the planet, and the most honest real thing I could do I haven't done.”

Part of the reason the TV star feels so confident about this next stage of his life is having found “the right girl,” his new wife, Caitlin McHugh.

“She's so beautiful pregnant. She's so magical,” he said of his bride. “She is the most graceful person I've ever met in my life, and she's handling pregnancy like a champ. Every day I say, ‘You're doing so great, you're doing so great.’ Just every day I'm with her I just realize first of all how lucky I am, but what a special human she is. She's magical. She floats into a room. I've never heard her say a bad word about anybody.”

The pair tied the knot in February and Stamos is looking forward to what’s to come. He’s so excited, in fact, that he doesn’t seem to have any pre-birth jitters.

“I'm not nervous at all. I've been not nervous about getting married -- I just knew it was the right thing,” he noted. “I'm not nervous about having a kid, I'm not nervous about having a kid with her.”

One concern that does give him pause?

“What if the kid comes out and doesn’t like Disneyland, doesn’t like musical theater?” he pondered, adding that there’s a Disney nursery. “I’m putting something very special in there this weekend!”

Benjamin will be released this fall.
