Nikki GrahameNikki GrahameAfter Friday night's Big Brother finale, we were bound to hear some more shocking revelations about the former Housemates.

Not least, Nikki.

It turns out that the 24-year-old, who is now girlfriend to winner Pete Bennett, has tried her hand at being an escort.

She admitted to having worked as a £500-per-hour escort girl, before The News Of The World made the revelation on Sunday.

But she insisted she had never slept with any of her customers - and the paper claimed that Babyshambles rocker Pete Doherty was one of them.

Breaking down, she said: "It's something I'm incredibly ashamed about. I made a big, big mistake - one I will regret for the rest of my life.

But boyfriend Pete, who basked in the glory of winning Big Brother's £100,000 prize, said he would stand by her.

He shrugged off the shame of Nikki's secret saying: "I've done much worse."

Nikki's new show, Princess Nikki, which would involve seeing if she could last a single day working various different jobs, could be called off, as a result of her shock revelation.

A boss at E4 told The Sun: "We need to chat to Nikki."

Nikki, Pete and the other ex-Housemates spent Saturday night partying at the Holiday Inn in Borehamwood, Herts, having had an emotional reunion.
