Have Mercy! John Stamos to Be a First-Time Dad at 54

Uncle Jesse is going to be a dad in real life.

John Stamos announced that he is expecting his first child with fiancee Caitlin McHugh, 31.

The 54-year old "Fuller House" star said that he always wanted to be a dad, but wasn't sure if it would happen because of his age.

"People would say, 'You should have a child.' I was like, 'That ship has sailed,'" he told People Magazine.

In October, Stamos proposed to McHugh at Disneyland after two years of dating. He decided to propose after finding out that she was pregnant.

"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 parent to ask, and it was like, 'You better!'"
