John Stamos recalls finding model girlfriend in bed with fellow celeb: ‘Worst nightmare’

John Stamos has shared explosive details about finding his model girlfriend naked in bed with a fellow TV star, leaving him “in tears”.

John Stamos claims he caught his then-girlfriend, model Teri Copley, in bed with fellow actor Tony Danza during their short-lived romance in the 1980s.

In his memoir If You Would Have Told Me, out Tuesday, the Full House actor revealed that he discovered Copley cheating with the Who’s the Boss? star one night.

“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, 60, wrote in an excerpt obtained by Entertainment Weekly.

“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.”

Initially brushing it off as Copley, 62, being busy at a modelling gig or an audition, Stamos wrote that he began to get concerned as time went on.

Remembering her ex-husband was in town, Stamos said he hopped in his car and drove to her place.

Upon arrival, Stamos discovered the house had “no lights on” and “no movement behind the windows” despite a car being in the driveway.

“A black 1957 Porsche 356 Speedster, vintage convertible. Strange. I shuffle to the car with my stomach sinking and take a quick look inside,” Stamos wrote. “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.”

Unable to enter the house from either the front or side doors, Stamos said that he remembered that he and Copley used to sleep in the guesthouse in the backyard.

“The blinds are closed, but the door is slightly open,” he continued. “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 recognise Teri’s a** barely covered by the sheets. It looks like her new poster,” the You star recalled, describing the moment as “my worst nightmare.”

“I try to hold back tears,” he shared. “Time slows until I’m frozen. I can’t breathe. A few tears roll down my face, and it p***es me off. They snap me out of my daze, and I feel angry and confused. I could explode.”

Stamos said he debated what to do next.

Ultimately, Stamos revealed that he decided to “run like hell” — but not before stealing the poster from the mysterious car.

“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,’” Stamos noted. “Tony? Who the hell is Tony?”

It wasn’t until Stamos was speeding home, and with a little help from a catchy Elton John tune, that he realised “the name of my rival.”

“Hold me closer, Tony Danza,” Stamos emphasised.

The Post reached out to Danza, 72, Stamos and Copley for comment.
