According to The Mirror, the glamour model made an appearance just before 11pm.

The newspaper said that Price was obviously a little worse for wear – and was sent away by Cowell after making her way to the top table.

Price turns up to Cowell’s party “drunk” originally appeared on We Love Katie Price on 4:00 pm.

According to the UK tabloid paper The Daily Mirror, the glamour model’s friends told Andre that she had offered to perform a sex act on James in a nightclub toilet nearly two years ago.  The shocking  revelation is thought to have triggered a breakdown in trust between the couple leading to Andre’s request for Price not to go out drinking without him.

Recalling Price’s alleged behaviour at London’s Movida nightclub, a source revealed: “Katie was hammered and determined to let her hair down. She was in the VIP section drinking heavily when she bumped into Duncan. She virtually launched herself at him, grinding up and down against him, and grabbing his crotch.

“Duncan was flirting back in a pretty innocuous way and kept reminding her she was a married woman. But Katie was having none of it and continued to make crude sexual gestures. She was bragging about her sexual prowess.

“She made some comment about not getting enough sex and basically suggested she took him into the toilets for a sexual treat he’d never forget. Duncan seemed unsure whether she was joking or not. But he reminded her again that she was married and declined her offer.”

Katie Price reportedly kept details of the proposition under wraps for almost two years before her pals finally spilled the beans.

The source continued: “Next day Katie was desperate to bury her actions and adamant that Pete must never find out. But eventually word got back and not surprisingly he felt humiliated and appalled. It broke him in two.

“It wasn’t the final straw but was most definitely a huge factor in their break-up – and one reason why he’ll never go back to her.”
