Katie Price once “flashed her boobs to Boris Johnson ” at a dinner party in Italy, Piers Morgan has claimed.
The claim about the mum-of-five comes as former Good Morning Britain anchor Piers wrote an open letter to his ex pal, urging her to seek help for her 'embarrassing train-wreck' of a life.
The journalist and TV personality, penned some brutally frank words for the former glamour model in an open letter addressed to her.
In the last few months Katie has endured love splits, arrests and endless rumours about her lifestyle.
But alongside his plea for her to get help, he has divulged some huge showbiz secrets.
He confessed that after 20 years as her friend he simply 'can't bite his tongue any longer'.
In his letter, published by The Sun, Piers wrote: "I remember being told by an impeccable celebrity source, who was there, about an outrageous dinner party in Italy a few years ago where you suddenly flashed your surgically enhanced cleavage at our now Prime Minister, Boris Johnson."
The stunning claim was followed by another, where he alleged Katie tried to have sex with him and was furious when Simon Cowell reportedly turned down her offer of a risque sex act on a string of wild nights out.
He added the page three favourite used to be his favourite celebrity, because of her honesty and candid nature - but says he is now very concerned for her.
He continued to list Katie's recent alleged dramas - including her bankrupt status, her past drug use, "endless new plastic surgeries" and the recent reports where she has been "been accused of repeatedly cheating on your fiancée".
"The shocking car crash you endured last September, which nearly cost you your life, should have been the moment to shake you into reality," he added.
Piers spelled out the further turmoil of Katie's life as he expressed his relief she survived before laying into her for her foolish and potentially deadly behaviour after she got behind the wheel when banned and under the influence of drugs and alcohol.
But sympathy was in short supply from Piers as he hoped - like a lot of her fans - that she'd come up against the turning point.
Piers continued his scathing rant condemning her for splashing the cash on a £179,000 custom-made pink Ferrari - which incidentally she can't legally drive.
He added: "To be blunt: I don’t want to wake up to news even worse than your horror smash.
"And nor do your five kids, to whom you’ve been a great mother in between all the mayhem."
Signing off, he wrote: "But right now, I’m finding it very hard to praise you for anything because everything you do and say these days smacks of someone who has jumped the shark from amusing entertainer to embarrassing train-wreck.
"WAKE UP, Katie.
"Don’t do it for me - do it for your children."
Katie recently split from fiancée Carl Woods but is thought to have rekindled contact after being spotted climbing into his Porsche this week.
The Mirror has contacted Katie's representative for a comment.
