BIG Brother champ Pete Bennett says he dumped show co-star Nikki Grahame because their sex life was RUBBISH.

He also branded the blonde “high maintenance” and said she kept insulting his pals.

Tourette’s sufferer Pete, 24, opened his heart just days after the romance came to the end — and ridiculed Nikki’s comments that the couple had fantastic sex.

Pete said: “She was never really interested, whereas my sex drive is very high!

“If I ever tried it on, she would have to finish her make-up or be looking her best.

“I wanted to cuddle in bed in the mornings. But she always seemed cold.”

Pete — who won £100,000 on the Channel 4 show — stood by Nikki, 24, when it was revealed she once worked as an escort girl. At the time he said: “I’ve done worse.”

But the final straw came when Nikki said his pal’s home in Brighton smelt “doggy-woggies”.

Pete said: “Her behaviour made me embarrassed. She was saying the place smelt ‘doggy-woggies’ and spraying perfume everywhere.”

Pete also told how fame went to Nikki’s head.

He said: “When we were at a party she was asked to help clear up. She said, ‘Have you seen an A-list celebrity working?’ and refused to do anything.”

He added: “She’s high maintenance.”

Pete admitted he dumped Nikki by phone because he was afraid to do it face-to-face.

He told Heat magazine: “I didn’t know how she’d be.”
