The News of the World can reveal the posh 43-year-old, who won the KitKat ticket draw to enter the BB house, is a lapdancer on the pub circuit, earning £100 an hour.
But she only does it for kicks. Her hubby Cosmo is a rich businessman.
Brunette Suzie-a mum-of-one with fake boobs, just like Lea-made her stripping debut at London hot spot Stringfellows, where one punter gave her a £10,000 tip.
However, we can reveal she now bares her FF boobs for £20 a time in a more downmarket venue, The Woolpack pub in Hayes, Middlesex.
Before each sleazy dance, Suzie passes round a cigar tin to collect the meagre donations from excited punters, usually 50ps or pound coins.
One man said: "I normally give £1 to the other girls, but I find Suzie particularly attractive so I give her £2. She makes my heart beat faster."
Suzie has also worked at The Olde Northwood in Pinner, Middlesex. Landlord Steven Pantling said: "She has a very good body for a woman in her forties. She stripped on stage and did one-on-one lapdances for paying punters. She loved working here and she worked in a few other places too."
Steven says he often wondered why she stripped, when she was so well off. He said: "She always drove to work in fast cars, so she wasn't short of a bob or two.
"Maybe she did it for the interesting people she might meet. Or to get noticed, she loves the limelight."
She was once painted gold from head-to-foot then writhed around naked for Finnish Goth-rock group, Him's video, Wicked Game.
Posh Suzie, who has a 21-year-old daughter Jennifer from a previous relationship, once lived in Chelsea, with Sol Campbell and George Best as neighbours. She recently moved to West Malling, in Kent, with her musician husband and dog. Before that she was a regular at trendy London nightclubs such as Chinawhite, but now she doesn't drink.
However Suzie has never abstained from flashing her boobs, doing dozens of raunchy photo shoots.
She had her breasts enlarged nine years ago and has vowed to compare them with Lea's-in front of the cameras. She said: "My bust makes me feel feminine, glamorous. And it gives me a sense of power."
A close pal revealed her nickname is Suzie the Floozie. She said: "She adores male attention and gets a thrill from seeing men gawp. But she's got a loving husband who understands her need to turn on other men. He knows she always comes home to him."
The friend said fame was the one ambition that Suzie hadn't realised, She added: "She's had money, the high life and mingled with stars, but never been publicly recognised.
"She'll be thrilled to be on Big Brother. She's tried desperately to get on for the last three years."
The stripper won her place in the house on Friday after Aisleyne picked her number. Suzie was given special privileges, like her own gold bedroom, bathroom and loo.
Brunette Suzie will also be the only housemate to nominate next week, although she hasn't been told her choices will automatically face the public vote.
