As John Stamos gears up to be a dad, he's surrounding himself with family and friends -- old and new!
The 54-year-old actor took to Instagram on Sunday to share a pic of his recent unexpected visitors. It appears Stamos had a surprise, mini ER reunion over the weekend, and judging from the photo, it looked pretty epic.
Goran Visnjic, Maura Tierney, Scott Grimes and Linda Cardellini were all in attendance, and at one point, they jumped in a photo with Stamos behind the medical drama's "old County General doors."
"My #ER cast came to my house for a visit," he captioned it, adding, "I keep everything" in reference to the doors taken from set.
The only thing that would make this picture better would be an appearance by George Clooney, who played Doug Ross on the TV series. Like Stamos, Clooney became a first-time father in his fifties when he welcomed twins Alexander and Ella with wife Amal in June.
We would have love to hear what kind of advice Clooney has for his former costar!
As ET previously reported, Stamos is expecting his first child with fiancée Caitlin McHugh, due in spring of 2018.
“I hope [to have kids],” the actor told ET just one month ahead of the 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.”
