Heather Mills McCartney has denied tabloid reports that she once worked as a £5,000-a-time lesbian prostitute.

The former model, who is soon to be divorced from former Beatle Sir Paul McCartney, denied the allegations claiming it was old news.

A statement from her lawyers said: “Heather Mills McCartney strongly denies the allegations. These are not new stories.

“The sources are clearly are a variety of unreliable persons who have been paid for their stories.

“The timing of the articles is clearly designed to cause maximum hurt to Heather, her husband and family at the sensitive time.”

Former prostitute Petrina Montrose told the News of the World that the 38 year old was a call girl who specialised in threesomes, citing one alleged night with an Arab prince, Adnan Khashoggi.

Montrose said: “Heather was a familiar face in our business.

“I knelt facing the Heather and we performed a sex act on the prince.”

A spokesman for the prince told the paper, “She has repeatedly lied. She was a hooker. I know. I paid.”

Lady McCartney looks set to receive around £200 million from her divorce settlement.
