John Stamos forgot he filmed ‘Big Fat Greek Wedding 2’: Hammered

John Stamos revealed while appearing on “The Howard Stern Show” Tuesday that his alcoholism had once been so bad, that he completely forgot he was cast in “My Big Fat Greek Wedding 2.” Even more, he doesn’t recall being on set.

According to the now-sober Stamos, he was hanging with cast mates Rita Wilson and Nia Vardalos in 2015 after being arrested for a DUI when they reminded him that he was expected to be filming in Toronto.

“I was just with Rita Wilson and Nia [Vardalos] in Greece and I realized, I forgot that the next day [after the arrest] they said, ‘Oh, you got to go to Toronto, you’re in My Big Fat Greek Wedding 2,’” Stamos, 60, recalled.

Stamos told Stern, 69: “I’m like, ‘What?’ I was hammered. I don’t remember being on that set.”

The “Full House” alum, who plays Wilson’s Greek-American boyfriend in the 2016 film, said that the minute he returned home from Toronto he was confronted by several friends, family members and even his agents.

“As soon as I came back from Toronto and ‘My Big Fat Greek Wedding,’ my sisters were there and my agents, and everybody was like, ‘Okay! It’s time,’” Stamos admitted. “It wasn’t even an intervention, it was like, ‘We packed your bags, you’re going.’”

Stamos also noted in the interview that he wasn’t mad at the so-called intervention and that he “went [to rehab] for 30 days.”

“I just knew it was time,” he continued. “That’s when I knew I was close to f–king up.”

The star has not had another drink in the last eight years.

Stamos recently told People that the photo of him in handcuffs, coupled with being arrested for a DUI, helped push him to stop drinking.

“I had to sober up. I was just drinking too much,” he told the publication ahead of the release of his memoir, “If You Would Have Told Me.”

“I just went low. I didn’t go high. I just surrounded myself with people I shouldn’t have been with.”

“I had that DUI and I was like, ‘I can’t do this. I’ve got to straighten up,’” Stamos continued. “That’s when I was confusing the universe because I’m not a bad person, but I was doing crappy things.”

Stamos’ wife, Caitlin McHugh, and their 5-year-old son, Billy, have helped him stay sober to this day.

“They have kept me on this path because going down the road of being sober and taking care of yourself, everybody tries,” Stamos told the outlet. “Everybody does it. You could get going for a little while. Then, it’s like, ‘I can drink again.’ So it’s staying on the path is what they mostly do for me.”
