• John Stamos has written a new memoir
  • Many revelations have come out including one with Tony Danza
  • Stamos caught the actor in bed with his girlfriend

Even the biggest studs can get cheated on, despite what many may think. Stamos and Copley dated back in the 1980s before his marriage to model Rebecca Romijn. At the time, Stamos was "dumbstruck and goofy in love" with Copley and described finding her in bed with Danza as his "worst nightmare." However, the actress insisted the two weren't actually together anymore when the incident happened.

"John has a very different recollection of what transpired decades ago," a representative for Copley told 'Fox News Digital'. "I wondered, 'What was John doing there?' because we had broken up," the actress also told 'People' magazine. "He just looked at me and shook his head, and walked away."

John had trouble getting over it quickly

The 'Full House' star described the incident to 'People' as "physically painful" and "worse than anything." Many who have experienced something similar will relate. "I can't explain it, but I would've rather been punched in the nose again or something because the pain is so overwhelming," he says. "Looking back, it's like, probably, she wasn't the right girl for me. So seeing him, realizing it was him and stuff, it was hard. I mean, it was awful."

Stamos recalled things going well between him and Copley for over a year before he noticed she had begun to distance herself from him. "I call her from the road, but the girl who breathlessly picked up the phone after one ring is now giving me busy signals and dial tones," Stamos wrote in his memoir.

"When I get home, I call her throughout the day and into the evening. No response. Strange. We've gone from talking on the phone every few hours to silence." Stamos drove over to Copley's home but discovered an unfamiliar car in the driveway. The home was dark and locked, but Stamos chose to check out the guest house.

"A black 1957 Porsche 356 Speedster, vintage convertible. Strange. I shuffle to the car with my stomach sinking and take a quick look inside," he writes in the memoir. "There's a hairbrush, keys, boxing gloves, and a half-unrolled poster of my girlfriend, naked, barely covered by a white sheet. Half of her butt is showing. I've never seen this poster before."

"The blinds are closed, but the door is slightly open," he says in the book. "I take a peek inside and see four feet protruding from the shabby-chic, floral-print duvet that once kept me warm. My Tiny Dancer is in bed with Mr. Porsche Speedster. They are sleeping. I can't tell who he is, but I recognize Teri's ass barely covered by the sheets."

John went into shock

At the time, Stamos didn't know it was Danza. "But I remember running down the driveway with tears streaming down my face and I didn't want anyone to see me," the actor told 'People' magazine. Stamos stopped and took a signed poster of Copley out of the unfamiliar car parked in the driveway.

"I stare at the two-dimensional, half-dressed woman that I thought I knew. She's signed the poster, with little hearts, 'My Dear Tony, I'll love you forever. XO, Teri,'" he recalls. "Tony? Who the hell is Tony?"

Stamos then admitted he didn't put together who the unknown man in bed with Copley was until he was listening to Elton John on the way home, discovering "the name of [his] rival."

"Hold me closer, Tony Danza," he wrote. Completely "breathless" at the sight, Stamos says he stumbled out of the room backward.

"At first I was like, ‘I'm going to kick his…’ I didn't know it was Danza yet. I see his abs. I'm like, ‘Maybe not. F--- it.’ And I ran," Stamos recalls. "But I remember running down the driveway with tears streaming down my face and I didn't want anyone to see me."

Stamos describes Copley as just a nice person, now. "I mean, it wasn't right to cheat on me, but I was too immature; I wasn't a man," he tells 'People'. "I didn't become a man for a long time and I think she was... I don't know. I was broken." John explained why he included this story in his memoir for those who might wonder.

"I really wanted to find relatable things that happened in my life. Because I think everybody thinks, like, ‘Oh, this guy's got no problems. I'm sure he's never been cheated on.’" John says that when people are cheated on, they "make a list."

"It's like, ‘Oh, she left me because I don't have enough money,’ or ‘I'm not good-looking,’ or this and that. And then you look at me and I go, ‘Well, he had all those things,’” he says. “People are s-----. And it's life."

John is currently happily married to Caitlin McHugh!
