Paul McCartney has instructed his lawyers to look into a British documentary due to be broadcast last night that depicts his wife Heather Mills as "a calculating gold-digger with a murky past", the Daily Mail has reported.
Printing a discreet picture of Mills from her days as a glamour model alongside one taken at her 1989 wedding to Alfie Karmal, the newspaper said the Channel 4 documentary portrayed Mills as "a lying fantasist who had long planned to ensnare a rich husband".
The paper said Sir Paul, 60, currently on tour in Europe, had declined to comment, but it understood he had instructed lawyers to speak to Channel 4, an independent broadcaster, and that he was "infuriated".
Yesterday, the Sun tabloid newspaper printed pictures it said depicted Mills, aged 18, baring her breasts at her first glamour modelling assignment.
The pictures, to be shown in the documentary, were apparently taken by Karmal.
In the film, Karmal says he was puzzled by his wife's frequent disappearances and at how she had once turned up in a new sports car.
Ros Ashley, described by the Mail as a "former pleasure wife" for rich Arabs, says in the documentary that she introduced Mills, then aged 18, to a number of wealthy Lebanese businessmen.
"Heather's ambition was to meet a wealthy man - whether Arab, English, Spanish, whatever would give her wealth and status," Ashley says.
Karmal's sister, Donna says: "She's very destructive. She's like a praying mantis when it comes to men."
And Mills stepfather Charles Stapley says Mills lives in "a confused fantasy world", suggesting her claims to have slept rough in London were exaggerated.
Channel 4's Matthew Robinson today said the company had held talks with Mills' lawyers throughout preparations for the film.
He would not comment on whether any legal action was pending, but insisted the broadcast would go ahead tonight.
Since losing a leg in an accident involving a police motorcycle in London in 1993, Mills has worked in charity, raising money for landmine victims.
She met former Beatle McCartney through her work.
They married in Ireland in June last year.
His first wife Linda died of cancer in 1998.
After initial difficulties, Mills' relations with McCartney's children by his first marriage are said to have improved.
