Big Brother winner Pete Bennett is back with his punk ex-girlfriend Cherry after sleeping with her while still dating besotted former housemate Nikki Grahame.

Body Pierced Cherry, 21, who has a shaved head apart from a long dyed red fringe, claims she lured tourette's sufferer Pete back after several secret trysts and that they have a 'deep connection' with each other.

The news of the rocker's infidelity will come as blow to 24-year-old Nikki's fragile mental health.

Nikki told New! magazine: "I've struggled with self-hatred all my life. Now I read all this stuff him and his friends have been saying about me and I hate myself even more.

"Pete wouldn't hurt an insect but he's totally destroyed me."

Cherry – real name Gemma Costin – told the Daily Star how they began dating before the reality show, split when he entered the house but later realised they had to be together.

A friend of the madcap rocker said: "Pete and Cherry had a fling which didn't work out.

"They met at a party recently and Cherry finally let him know how she felt. Pete loved Nikki but she pushed him too far. He thinks Sherry is wonderful."

Meanwhile, members of Pete's band Daddy Fantastic are furious with the singer for dumping them to sign a solo deal.

Guitarist Wobbly Bob told the Daily Star: "For a man with a d**k that big he doesn't have any balls."
