It’s been a big year for Fuller House star John Stamos! Two months after getting engaged to Caitlin McHugh, the actor has revealed that he and his fiancée are expecting their first child together.

“I’m going full adult,” Stamos said to People about the news. He added that being a father is something he’s wanted for a while and now, at 54, he’s more than ready — thanks in part to all that on-screen practice. “I’ll be a fun dad. I’ve been practicing for a long time,” he joked. “I’ve done every schtick you can do with a baby on TV … all the bits and jokes and diaper gags. I’ll probably just do all that stuff.”

McHugh, for her part, has no doubts that her husband-to-be is ready for the job. “I greatly admire his originality, creativity, ambition, work ethic, and humor — all qualities I’m sure he’ll pass down to his child,” she told People. “He’s always been wonderful with kids, and I’m sure he will be an amazing father.”

Stamos revealed that he and McHugh found out they were expecting before getting engaged. The news was a push to propose, he said, but it was in the cards anyway. “The [pregnancy] happened. Then I said, I better have a ring on her finger because it’s the right thing to do, and I wanted to marry her anyway,” he said. “So I called her parents to ask, and it was like, ‘You better!'”

The pair got engaged in October after Stamos pulled off a romantic Disneyland proposal. So far, they haven’t revealed their due date or the sex of their baby, saying of the latter that they prefer to be surprised. Congrats to the growing family!
