The 54-year-old actor shared a hilarious photo on Instagram on Thursday from a Full House episode where he's wearing a faux baby bump and a t-shirt that says "bun in the oven." Stamos and his wife, Caitlin McHugh, are expecting their first child together -- and the former Grandfathered star can't wait to meet his bundle of joy.
"This is the longest 9 months of my life! #cantwait 4 #fatherhood," Stamos wrote alongside the throwback still.
Full House fans can recall the episode where Uncle Jesse and a pregnant Becky (Lori Laughlin) made a bet that Jesse wouldn’t be able to last one whole day wearing the baby bump. Whoever wins got to choose the wallpaper in their bursary. Ultimately, Jesse lost and didn't get to put up his Elvis Presley wallpaper up.
Stamos has been gushing non-stop about his baby on the way. Earlier this month, he shared a throwback of his late father, Bill, lovingly looking at his newborn son.
"Can’t wait to look at my baby like this. #BillStamos #Ordinary Hero," he captioned the tender shot.
Stamos and McHugh tied the knot on Feb. 3 in an intimate ceremony at Stamos' Beverly Hills home after getting engaged at Disneyland in October of 2017. In December, they announced that she was pregnant with their first child.
"I hope [to have kids]," Stamos told ET in November, before McHugh's pregnancy announcement. “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 and I finally found the right woman -- the perfect woman.”
Since then, the couple have been head-over-heels and anticipating the arrival of their baby.
