Charlie Sheen, Brooke Mueller had threesome

London (ANI): Charlie Sheen and wife Brooke Mueller reportedly enjoyed menage À trios with another woman during their 21-month marriage.

The alleged threesomes were said to have taken place before the Two and Half Men star was arrested for threatening Mueller with a knife during a booze-fuelled argument.

"Brooke is bisexual. She and Charlie have had more than one woman share their bed in the short time they've been married," the Sun quoted a source as saying. The insider added to a US website: "Some of the women they slept with also did drugs with them."

The couple, who share two children, was apparently receiving treatment for drug and alcohol problems.
