Debbie Reynolds says Liberace's sexuality was an open secret among the pianist's friends.

Reynolds plays Liberace's mother Frances in the film Behind the Candelabra, which premieres in the United States on HBO on Sunday.

The film, which stars Michael Douglas as Liberace and Matt Damon as his lover Scott Thorson, premiered Tuesday at the Cannes Film Festival in France, where it is competing for the prestigious Palme d'Or award.

In an interview with the AP, Reynolds recollected being part of Liberace's inner circle while both were performing in Las Vegas. Liberace died at the age of 67 without publicly acknowledging his sexuality.

“I have never had a better time than being Liberace's date,” Reynolds, 81, said. “We all knew he was homosexual. That was a friend: You know what they love and the people that they love, and what they are.”

“I don't want him to be remembered just for being homosexual,” she added. “He should be remembered as a great entertainer and loved by so many. And this picture does that.”
