The biggest Brit split since Charles and Diana pits a beloved Beatle against an anti-land mine campaigner. U.K. papers say they have court documents alleging that McCartney physically abused his wife during their four-year marriage and denied Mills McCartney, who has a prosthetic leg, use of a bedpan at night. His lawyers say they'll vigorously defend against such allegations, and the Beatle is mostly keeping mum, except for admitting that he has started seeing a psychiatrist. The pair have a toddler named Beatrice and, despite McCartney's $2 billion fortune, no pre-nuptial agreement. The good news is, we can no doubt expect some classic breakup tunes to come from this sad story.
