It looks like Uncle Jesse and Aunt Becky might be expanding their family by one more.
“Is that Jesse and Becky’s new kid?” the 53-year-old actor captioned the shot. “Watch Fuller House Season 2 to find out!”
Of course, the real question should be, “Is that Marcel from Friends?” The primate bares a striking resemblance to the female monkey who played Marcel on the hit NBC show – who goes by the name Katie.
Friends wasn’t Katie’s only starring role. She’s also had roles in 30 Rock, Victorious and Bruce Almighty. She even starred alongside Kendall Jenner in a 2015 Allure Magazine cover shoot.
Well good news — it is! Reps for the Netflix series exclusively confirm to PEOPLE that the lovable animal will be joining the cast for an episode next season.
As for Stamos and Loughlin, their days of monkeying around on the Full House sequel set are over for now. The show wrapped up its production over the weekend, shooting its last scenes with its live studio audience.
