John Stamos Claims Ex Teri Copley Cheated with Tony Danza, Copley Denies Allegations

John Stamos describes heartbreaking moment in new memoir, leading to a public dispute with ex-girlfriend Teri Copley about their relationship status at the time.

In his new memoir, John Stamos alleges that he caught ex-girlfriend Teri Copley in bed with actor Tony Danza, leading to a heated public dispute about their relationship status at the time.
Copley, however, insists they had broken up by the time of the alleged incident, while Stamos disputes this claim, doubling down on his statement that they were still together.
In his book, Stamos describes the ordeal as his 'worst nightmare,' and notes several times that he was 'so brokenhearted' over Copley's alleged infidelity.
While Stamos was on the road with his band, he noticed that his communication with Copley abruptly ended, which led him to drive to her home and discover her 'cheating.'
In an interesting twist, Stamos later thanks Danza in his memoir for indirectly helping make 'Full House' a hit, stating that ABC decided to air Danza's show 'Who's the Boss?' ahead of summer reruns of 'Full House' to boost audience interest.
