Sir Paul McCartney's estranged wife Heather Mills is reportedly "disgusted" by his new girlfriend Rosanna Arquette for her controversial role in 1997 movie CRASH. The former model - who lost a leg in a motorcycle accident in 1993 - is sickened by Arquette's portrayal of a disabled woman who gets sexual enjoyment out of car accidents in the David Cronenberg-directed movie, according to a pal. Mills' alleged attack follows reports of a romance between the ex-Beatle and the Hollywood star, which first surfaced last month (Nov07). A close friend says, "When Heather saw Paul's new girlfriend appearing on screen with a similar injury to herself, she was disgusted. Rosanna's character gets turned on by accidents. Heather told pals she finds this reprehensible." Mills and MCCartney - who have a four-year-old daughter, Beatrice, together - are currently embroiled in a bitter divorce battle.
