John Stamos' Memoir Reignited Decades-Old Drama With His Ex Teri Copley

John Stamos' bombshell memoir revealed that the actor's ex-girlfriend, Teri Copley, not only cheated on him but that Stamos walked in on her in the act. According to "If You Would Have Told Me," Stamos decided to check on Copley after she cut him off following his return from touring with the 1960s icons, Papa Doo Run Run. Stamos recounted observing an unfamiliar car in Copley's driveway upon arriving, which had a partially dressed poster of hers inside. Unable to get into the house, he ventured to the guesthouse, where Stamos discovered more than he bargained for — Copley cuddled up with a mystery man.

"My heart is beating out of my chest," Stamos recalled. "My mind is racing, and the room is spinning. It's my worst nightmare," (via USA Today). According to Entertainment Weekly, the "Full House" star briefly considered confronting them but changed his mind upon noticing her lover's muscular physique. With tears streaming down his face, Stamos left the property, but not before taking the poster from the car. As he revealed, "[Copley] signed the poster, with little hearts, 'My Dear Tony, I'll love you forever. XO, Teri.' Tony? Who the hell is Tony?"

It was only during his drive home, accompanied by Elton John's "Tiny Dancer" on the stereo, that Stamos realized the Tony in question was Tony Danza. "Hold me closer, Tony Danza," he wrote. However, following the release of Stamos' memoir, Copley swiftly denied the allegations.
