John Stamos Will Finally Be a Dad in Real Life

The 54-year-old actor and his 31-year-old model/actress fiancée Caitlin McHugh are having a baby, the couple confirmed to PEOPLE. It's the first child for Stamos, who is most famous for portraying Uncle Jesse, a beloved TV sitcom character the world watched mature into a fine father over the course of "Full House" (and again on "Fuller House" when he had another kid).

"We have the same morals and the same values, that all clicked nicely. So we said, 'Oh, well, maybe we should have a family,'" Stamos told the publication. He continued, saying McHugh said, "'Maybe we should have a kid [before we get married]' and I said, 'Why?'"

Her response: "Because you're old." Touche.

"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 added. "So I called her parents to ask, and it was like, 'You better!'"

Stamos and McHugh engaged at Disneyland in October, after he popped the question inside California Adventure with a "Little Mermaid"-themed proposal. The two have been dating for nearly two years.
