Katie Price threatened to stab clubber

Katie Price allegedly threatened to stab a clubber during a drunken night out on her Ibiza holiday.

The British glamour model – whose husband Peter Andre walked out on her five weeks ago – made violent threats, flashed her underwear, danced on tables and called a fan "ugly" during the wild 12-hour drinking session on the Spanish Island.

Things turned nasty when Katie, who had been partying at Eden Nightclub on Tuesday night (16.06.09), lashed out at a girl who she believed to be a friend of Peter's, threatening to "cut" her.

According to Britain's The Sun newspaper, a source claims Katie told the girl: "I'm gonna cut your f***ing face. I swear I'll cut you."

Another onlooker added: "She just lost the plot. Everyone just looked at each other shell-shocked. It was sick."

Katie – also known as Jordan – was also reportedly seen getting close to a pair of hunky men, was seen chatting to ex-boyfriend Matt Peacock and is alleged to have kissed male model Anthony Lowther, 28, during her wild night.

A source told Britain's Daily Mirror newspaper: "There was chemistry between them. When she jumped on to the podium next to the DJ booth, she moved her body up and down seductively against his.

"Katie was acting as if her behaviour was totally normal. It was like she was putting on a show for everyone there. She was saying, 'I can do this now, I'll be divorced in five and half weeks'."

Earlier in the night when attending a show by pop duo The Ting Tings at the Ibiza Rocks hotel, Katie reportedly refused to pose for a photo with a fan, saying: "No, I'm not having my picture with you. Another thing, I should let you know that you're ugly. Really ugly."

The 31-year-old model is holidaying with eight friends on the Mediterranean island, where she is filming her first solo reality TV series and shooting a new calendar.

Estranged husband Peter is currently holidaying with the three children they raise together in Cyprus.
