DYE HARD

TOP British hairdresser Nicky Clarke is cheating on his famous girlfriend with a £110-an-hour hooker, we can reveal.

The superstar stylist has been sneaking busty call girl Natalie Springer into his £2.5 million home for sex behind the back of celeb interior designer Kelly Hoppen for THREE MONTHS.

Clarke, 49, first bedded Natalie just DAYS before receiving his OBE from the Queen in February.

The crimper-whose hair products empire is worth £50 million-was still at it with her last week-even trying to CUT the price of his romps.

"We were doing it for three hours," says Natalie. "Then, as I was about to leave, he rushed out of the room and strolled back in naked counting a wad of notes. He asked me, 'Is one fifty all right?'

Breasts

"It was £180 short- but he was so good at it for his age, and I'd got so close to him, that I said OK. I was just surprised he wanted a cheap hooker like me when he has such a glamorous girlfriend," adds the beauty whose enormous 32-GG breasts have been boosted by two boob jobs.

It was the first of a series of trysts the TV hairdresser had with 26-year-old Natalie-including a baby oil-drenched THREESOME with a female celebrity.

Randy Clarke's appetite for sex is renowned. His cheating led to his split him from wife Lesley in 1995. They are not divorced and are still good friends-they even live in the same street.

Four years ago we revealed how he had a three-in-a-bed session with two holidaymakers while away with his estranged wife. But since falling for Kelly 11 months ago, Clarke has been trying to cultivate a respectable public image.

Only last month the couple sold the story of their relationship to Hello! telling why they are "so well-suited" and featuring her design touches to his north London home.

Kelly, 48-whose clients include stars such as the Beckhams-said she was "definitely in love" but added that it was "difficult to get Nicky over to the other side of the river" where she lived in Battersea.

Today she'll know just why.

Natalie says: "Nicky likes to give the impression he's a smooth guy in a committed relationship with Kelly-but in reality he's just a dirty old sleazebag living a lie.

"He pretended to me he was a single bloke called Andrew and used that name for all our meetings. But I've seen him on the TV and in magazines-and anyway his bathroom was full of Nicky Clarke shampoo and conditioner."

Clarke-renowned for the hairstyles of clients from Princess Diana and Sarah Ferguson to David Bowie and supermodel Sophie Dahl-first booked Natalie in early February at around midnight after returning from a trip to Geneva.

He contacted a London escort agency asking for a girl to be sent to his home in trendy St John's Wood.

"He handed me £110 as soon as I arrived," explains Natalie. "It was dark in his hallway, lit by Jo Malone candles, and he was shy about showing me his face. His hair was flopped over it-but after we had sex it was off his face and I recognised him.

"He stripped off and I began pleasuring him," says Natalie. "I was wearing a little black dress and I took off the straps and let it drop to the floor. Nicky loved my bum.

"He had a bottle of baby oil and began pouring it all over my buttocks then massaged it in. He's so energetic for his age. He's 49 but you wouldn't know it."

Slowly Natalie began to fall for her regular client. "I never felt like it was just sex with me and Nicky, it was more than that. The kissing was passionate and intense," she says.

"He was so sensual. He loved putting his fingers through my hair and oiling it. After sex we'd lie there naked and Nicky would chat. He said he was well travelled and he'd take me somewhere nice one day." He'd also chat about his love of bargains.

"Nicky said the white cotton bedding we were making love on was from Primark and that he shops for lots of stuff there including clothes," says Natalie. "Thinking about it now it's hilarious-because his girlfriend has her own bedding range."

On March 15 Clarke-whose showbiz clients include Kate Moss, Gwyneth Paltrow and Brad Pitt-took their encounters to a new level with a famous beauty.

In the early hours Natalie got a text from him saying, 'Would you do a threesome with a female who is here now x'.

She recalled: "When I got there Nicky took me to the bedroom and the woman was laid on the bed in a black silky dressing gown."

Stroking

Natalie started the ball rolling by peeling off her black dress. "The woman began stroking me," she says. "But I didn't find her attractive. She was wearing too much mascara and looked a mess."

As £450-a-haircut Clarke watched, the women kissed and caressed each other. Natalie says: "I reached into Nicky's gin and tonic and got some ice out then started rubbing it over the woman's body. She went wild for that."

Natalie-who has recently changed her name by deed poll to Jet Black-felt the other woman was jealous of her good looks.

"She wouldn't let me and Nicky do anything together and I could tell he was dying to get his hands on me," says Natalie. "He was being passionate with me and it seemed to p*** her off-but they were both quite drunk. It wasn't a success."

Clarke-who earns £5million a year from his products and salons in London, Manchester, Birmingham and Leeds-paid Natalie £200 in cash for the threesome.

After that night he wanted their meetings to become even more secretive-and asked Natalie to stop wearing the kind of skimpy outfits that would give her job away to his neighbours.

His estranged wife Lesley- managing director of his hairdressing empire-lives just five doors down.

"Once I arrived at his place wearing a fur coat with a little black thong and stockings on underneath," says Natalie.

"I dropped the coat and he was horrified. He said, 'You should wear more clothes when you come around'. But I liked to tease Nicky. The last time I went over I wore thigh-high PVC boots and a tiny boob tube dress. He opened the door and groaned, 'Oh my God-you need a coat!'"

She says after their romp Clarke made her leave barefoot with her boots in a carrier bag and her body shrouded in a hairdressing gown.

Natalie's revelations will devastate Kelly. The redhead-who designed her friend Posh's LA mansion-began dating Clarke last summer after they met at an Elton John party. They were together at Geri Halliwell's tea party book launch at London Zoo last Sunday. She is also Sienna Miller's stepmother and an ex of footballer Sol Campbell.

Natalie says: "I think Nicky's convinced himself that because he's paying for sex he's not cheating. But I think that makes his behaviour worse.

"I know it sounds stupid but I got so close to Nicky I thought that we could end up as boyfriend and girlfriend.

"But then as I got to know him better it was obvious he just wanted me for sex. I was just like a piece of meat to be paid for his pleasure.

"Once he had satisifed his lust, he couldn't wait to get rid of me

"He seemed ashamed of me too wanting to cover me up in case his wife and posh neighbours discovered our guilty secret.

"He is living a lie. Now Kelly will know what he's really like. She should dump him."
