'Behind the Candelabra' HBO Movie: Scott Thorson, Ex-Boyfriend of Liberace, Claims Michael Jackson Was His Lover

Scott Thorson, once Liberace's much younger boyfriend, claimed he had an affair with the late Michael Jackson, The Daily Mail reported June 7.

Thorson's memoir Behind the Candelabra tells the story of his 6-year relationship with Liberace, which started when Thorson was 17 and the entertainer was 57. The book is the basis for the upcoming HBO movie of the same name.

Thorson, 54, said Liberace introduced him to Jackson in the late 1970s, according to The Sun.

"It was right around the time Thriller was coming out and Michael and I became lovers," Thorson said.

He claimed his relationship with the King of Pop lasted between six and seven years.

"Michael was very generous, too. He treated me well," Thorson said.

Thorson also spoke about his relationship with Jackson after he gave an interview to The National Enquirer in 2004 and claimed first sexual encounter with Jackson took place at the home of the late female impersonator Danny La Rue.

Thorson claimed that Liberace made him get plastic surgery so he would look as if he were the pianist's son.

He filed an unsuccessful $113 million lawsuit against Liberace after their breakup.

The Steven Soderbergh-directed film also stars Matt Damon as Thorson, Scott Bakula, Dan Aykroyd and Debbie Reynolds.

Soderbergh revealed that the movie was rejected as "too gay" by every major American studio and that that was the reason the film had no American theatrical release before the cable network HBO took the project.

"Matt Damon did a great job playing me and he did a great job in bed with Michael Douglas too," Thorson said.

Thorson, who was recently in jail while awaiting sentencing for burglary charges, said he was disappointed that he did not make more money off of the project. He said he was also dismayed that neither Douglas nor Damon came to bail him out.
