Dec. 13 (UPI) -- John Stamos is going to be a first-time dad.
The 54-year-old actor announced in an interview with People that his fiancee, 31-year-old actress Caitlin McHugh, is pregnant and expecting a baby in 2018.
"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."
Stamos and McHugh are keeping the baby's sex secret, although the Fuller House star did say they may have more children in the future.
"I think so," he shared. "Caitlin wants to have other kids too."
Stamos and McHugh got engaged in October after about two years of dating. The actor said in an interview with Entertainment Tonight the following month that it would be "a tragedy" to not have children with McHugh.
"I hope [to have kids]," he said. "That's always been my plan. It's just taken me a lot longer than I anticipated. It would be a tragedy if I didn't have children, I think. I finally found the right woman -- the perfect woman."
"We're baaaack! Dec. 22nd. @netflix #FullerHouse," he wrote.
