The former Mrs. Paul McCartney will be outed as a lesbian call girl by fellow former pro Denise Hewitt as part of Heather Mills: What Really Happened, a television documentary to debut on the UK’s Channel 4 on Tuesday night.

“We have a naughty background. We went into high-class prostitution behind closed doors,” Denise spills. “There were 10 of us…. We would have full-on sex with a guy. We’d do girlie-girlie scenes. Always girlie-girlie scenes. I mean 99.9% of men like a girlie- girlie scene. ”

“We used to get a lot of jewelry as gifts – rings, watches, Bulgari bracelets, cars. The world was our oyster. We enjoyed it,” Denise explains of the perks that accompanied Heather’s tenure as a sex worker.

Heather first sparked rumors that she had once worked as a lady of the night after she her participation in a German porn photo-book showing off how to have good sex was exposed 2006.
