Joan Collins has angrily denied rumours that her marriage to Percy Gibson is a sexless sham.

The former 'Dynasty' star said that e-mails being sent to the press claiming that the couple had been sleeping in separate beds were lies.

"I find it very sad that someone is spreading this stuff," the 68-year-old told the New York Post. "We're extremely happy and very much in love. We couldn't be happier."
