John Stamos to Become a Dad at Age 54

The house of Stamos is about to get a little fuller. At the age of 54, America's favorite TV uncle, John Stamos, is about to become a father for the first time.

Stamos revealed to PEOPLE Magazine that he and his fiancee Caitlin McHugh, 31, are expecting their first child.

The couple got engaged back in October when Stamos proposed at Disneyland by using a video compilation of Disney love stories. 

I asked...she said yes! ...And we lived happily ever after--

John tells the magazine that he wanted to propose to Caitlin when the pregnancy happened because it was "the right thing to do."

Meanwhile, McHugh jokingly told the magazine that she told Stamos they may want to have a kid before they get married because he's "old." 

Both parents-to-be gushed to the magazine about their excitement for the upcoming arrival.
