John Stamos Expecting First Child at 54

Actor John Stamos is going to be a dad for the first time!

Stamos told People magazine, “I'll be a fun dad. I've been practicing for a long time. 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.”

The baby news comes just months after he proposed to Caitlin McHugh, 31. He said, “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. So I called her parents to ask, and it was like, 'You better!'“

Caitlin opened up on his reaction, saying, “The look on John's face when I told him we were pregnant was priceless. It was the look of a man who has wanted a family of his own but wasn't sure it was going to happen for him. Now it is!”

Of his decision to have a family with McHugh, the 54-year-old said, “We have the same morals and the same values, that all clicked nicely. So we said, 'Oh, well, maybe we should have a family.'”

How does Caitlin know he'll be an “amazing father”? She gushed, “I greatly admire his originality, creativity, ambition, work ethic and humor — all qualities I'm sure he'll pass down to his child. He's always been wonderful with kids.”

As for more children in the future, Stamos shared, “I think so. Caitlin wants to have other kids, too.”

In October, Stamos told "Extra" that having children was "certainly the plan."
