GENERATION JIM'S OLD FLAME ON THE GAME AS pounds 500 VICE GIRL.
TV Generation Game girl Debbie Corrigan offers wealthy punters group sex and lesbian romps with a Playboy model.
The busty stunner offers sex for cash through a top London madam, it is claimed.
Her seedy secret will stun her legion of fans on the BBC family show.
Debbie, 27, has teamed up with Gaynor Britt Royle - the ex-girlfriend of Coronation Street star Martin Hancock, who plays treetop protestor Spider Nugent.
Debbie is said to have offered pounds 2,000-a-day deals for foursomes with two undercover reporters who were posing as businessmen.
She got her taste for the high life while dating top funnyman Jim. He left his fourth wife Tracy Hilton to set up home with Debbie.
But she is understood to have turned to her new life of high-class sex trade after splitting with Jim last year.
Debbie moved out of his pounds 1.4 million mansion in Surrey and uses her vice girl job to fund a mortgage on a posh Chelsea apartment.
She turns up for "dates" in a top-of-the-range Porsche Boxster in a designer black ballgown.
She meets her sex-hungry clients in top London hotels, including the five-star Grosvenor House.
She tells them: "You must wear a condom."
The busty pin-up, who has also dated 6ft 4in England rugby hunk Chris Sheasby, met Jim on the Generation Game in 1996. After a couple of appearances she was offered a starring role in a new version of his X-rated touring panto Sinderella.
She had her enormous 32H boobs reduced to keep the top comic happy - after TWICE having them increased.
But the showbusiness pair had a series of rows and Jim accused the blonde of having a secret affair.
Despite the split with Jim, she continued on the Generation Game.
But Debbie is believed to be unhappy with the cash she earns from the show - pounds 300-a-day.
And her sordid sideline is allegedly far more lucrative.
She makes thousands of pounds from selling herself to super-rich clients from the Middle East, it is claimed.
Twice-married Debbie is the eldest of three sisters. The youngest is a nurse working in London and the middle one has a photography job in Manchester.
Brunette Gaynor Britt Royle, 24, who also bedded Manchester United star Dwight Yorke, once posed nude for Playboy magazine and has also been a lap-dancer.
Debbie recently told the Sunday People how her huge boobs drove her to the brink of a nervous breakdown.
She spent more than pounds 22,000 on five cosmetic ops in her quest for a perfect cleavage.
But the surgery made her life a nightmare.
And Jim ordered her to reduce their size to boost their sex life. She now entertains punters with a reduced 32D bust.
Debbie said: "I am 100 per cent happy with the way I look now.
"These past two years have been a living nightmare and I went through hell. I took the happy drug Prozac but nothing made me feel better."
But she admits she has always enjoyed a raunchy sex.
Talking of making love to rugby star Sheasby she said: "I've told him I'll dress up in suspenders and stockings if he makes love to me in his full rugby kit."
Last night stunned Jim Davidson said: "I don't believe a word of all this.
"I don't see Debbie any more as a girlfriend.
"But I've known her long enough to realise that she is not a hooker.
"This could all have been a big wind-up but I would be astounded if it were true."
Debbie denied the claims and said: "It is not what I'm doing. I'm too high profile to do that.
"No way at all, I'm not happy. It's one big set-up."
Last night Gaynor Britt Royle was unavailable for comment.
