BIG Brother's sex-hungry blonde Helen has vowed never to get back with boyfriend Big G — so the scene is now set for a full-scale romp with hunky housemate Paul.

Evicted contestant Josh revealed Helen's saucy decision after he was booted out on Friday night.

"She won't be seeing Big G after the show," he declared. "She's split with him from inside the house."

Meanwhile dizzy hairdresser Helen, 23, is still unaware that Big G — 30-year-old mining geologist Gavin Cox,  from Cardiff — has already given her the Big E after being humiliated by her flirty on-screen antics with car designer Paul.

In a heart-to-heart chat with Elizabeth in the early hours of yesterday, Helen confessed she was craving sex after seven weeks locked in the house under the gaze of Channel 4 TV cameras.

"I haven't had it for ages," she said. "It's such a long time to go, especially when you're used to getting it on a regular basis."

But she was making plans to spend last night in the Big Brother den with Paul, who earlier scrawled "I love sex" on her back in yellow paint, pictured left, and who dubbed the den "the James Bond love shack".

The sexual tension built yesterday as wannabe Page 3 girl Helen and 25-year-old Paul enjoyed a pillow fight.

Earlier they had their first tiff. Vain Paul threw a tantrum when Helen said she didn't like his lemon-coloured shirt.

Paul has boasted about his sexual physique and prowess — but he wimped out when Helen offered him passion on a plate after their romantic meal together this week.

Evicted Josh, 32, yesterday added a new dimension to the game — claiming Paul doesn't really fancy her and is stringing the saga along to win more backing from viewers.

"I think Paul's on to a vote-winner with Helen, but I don't think he's interested in her," he told us. "He's hanging in there with her for that reason. It's a little bit staged for him. He's playing the heterosexual romantic guy and it looks good.

"I think Helen should be careful because he's playing a very shrewd game. And, in her naivety and innocence, she's loving it and going along with it."

The tactic appears to be working because Paul avoided being nominated for eviction this week — for only the second time in the whole series.

And the will-they-won't-they story has done wonders for Helen, too.

Josh, pictured right with host Davina, copped 84 per cent of the viewers' venom and pulled 1,219,834 votes. But Helen has soared to the top of the latest popularity poll on the Big Brother website with 49 per cent of the vote.

After being greeted out of the house by presenter Davina McCall, former millionaire and ex-bankrupt Josh said he reckoned he was sent packing instead of Helen because fans are desperate for her to bed Paul.

"One of the reasons I was voted out was the way their relationship blossomed in the last week—especially with the romantic meal," said Josh. "It really started to kick off.

"It had been happening before, but this week there was the crescendo. It's a mad, bad relationship. Sometimes you'll say to them, ‘Christ, you two, will you just shut up!'

"They're with each other all the time, having little digs, little sarcasms and innuendos."

But Josh believes Helen and Paul WILL finally do it — as long as Big Brother lays on enough alcohol.

"They never gave us enough booze," he said. "If they want a really big story, they've got to give them more.

"Helen really loosens up and gets a bit naughty with more alcohol."

And although Josh wants Dean or Elizabeth to win, he is convinced either lovestruck Helen or Paul will scoop the £70,000 first prize, beating the red-hot favourite, gay air steward Brian.

"I think those two will tease you all the way," said Josh. "They won't let you know what's happening.

"Even we didn't know what was going on a lot of the time, because they kept sneaking off to the den. They keep having these secret rendezvous and whispering all the time.

"Helen does feel bad about what she's doing to Big G, but she's just going along with it. Why not? It seems to be working — and it's proving popular.

"Brian said Paul told him he actually does like her, but I'm still not sure."

So did the other housemates feel left out when Helen and Paul were flirting?

"No," insisted Josh. "We just thought, ‘It's happening, let it go, let it blossom.' We were aware that it was probably hogging all the headlines outside the house."

Josh told his housemates he was gay — he runs the Outlet property lettings agency for gays and lesbians in central London. But, in fact, he's bisexual and had sex with a woman as recently as eight months ago.

And he confessed that he found the girls in the house far sexier than the boys! "I do think Helen is very sexy in a bubbly sort of way," he said.

"But the person I most wanted to sleep with was Amma. She's got a great body."

He admitted he, too, desperately missed sex in the Big Brother house and even botched up the dancing task because he woke up in an excited state and couldn't get out of bed quick enough!

When Josh was brought into the house later than the rest he promised "nudity, nocturnal activities and naughtiness". He delivered none.

"It was a struggle," he said. "The whole time I was trying to bond with people and play catch-up because they'd already been there for two weeks.

"Within a few days, I had a huge slap-down from Brian who is so central to the group. I just took a step back and tried to be calm. I was suppressed — they didn't get to know the real Josh. It's very stressful in there and you do get paranoid. People aren't being themselves."

He reckons gay air steward Brian probably did want to bed him and that was one of the reasons for the tension between them.

"Maybe he does fancy me a little bit, but who knows," said Josh. "We didn't hit it off at all. And I didn't fancy him at all."

Josh loved to flaunt his tanned body in the house. But, denied regular visits to the gym, he was horrified when his pecs disappeared.

"They've gone south," he said. "I've now got a nice tummy to keep me warm!

"I went in there saying I was going to do a lot of exercise but, to be honest, I didn't want to look a complete t***** with the weights and stuff.

"It's very hot in the house — that's why I was bare-chested all the time. It was like being on holiday."
