Someone Spying on Paul?

SOMEONE'S SPYING ON THE 'CUTE BEATLE'!! The Paul McCartney/Heather Mills divorce is getting really ugly, says MSNBC.com and Britain's Sunday Mirror.

Reports say Mills got her hands on a taped phone conversation between McCartney and his daughter Stella, the fashion designer. In the tape, Stella, no fan of Mills to begin with, reportedly tells her dad she believes allegations that Mills was a high-class hooker, a charge former model Mills has denied.

"Paul's face went white as a sheet and he looked utterly stunned," when Mills played the tape for him, reports the Sunday Mirror. "He was shocked and staggered to discover that his private home phone had been secretly bugged."
