The former Culture Club singer, tried under his real name George O'Dowd, was accused by Norwegian Auden Carlsen of handcuffing him in his London home and beating him with a chain.
O'Dowd, who denied one count of false imprisonment, said that Carlsen had hacked into his laptop and stolen photographs. He told police that he had handcuffed the escort to the bed while he investigated the laptop tampering.
Carlsen, 29, told Snaresbrook Crown Court that O'Dowd had fabricated the story about the laptop so that he could punish him for not having sex when they first met.
"I think he couldn't handle the refusal - me not having sex with him," he said.
O'Dowd did not give evidence during the trial. He will be sentenced on January 16.
