Sir Paul McCartney's estranged wife Heather Mills has upset autograph hunters in Los Angeles by turning down those who ask her to sign merchandise associated with the former BEATLE. The ex-model reportedly refused to pen her name on a copy of vintage Beatles album MEET THE BEATLES because of the link to her husband, who she is currently divorcing. When presented with the memorabilia, Mills is reported to have said, "You've got to be kidding - I refuse to sign this." A source tells British newspaper the Daily Express, "She then shoved the album back at the man and stormed off. "Given how acrimonious her divorce from Paul is turning out to be, it perhaps wasn't the best thing to ask her to inscribe."
