LONDON - Lawyers for Paul McCartney said Wednesday that the former Beatle will “vigorously” defend himself against allegations made by his estranged wife, Heather Mills McCartney.

Britain’s Daily Mail newspaper on Wednesday reported details of an alleged court document containing accounts of acrimony and mistreatment during their four-year marriage.

“Our client will be defending these allegations vigorously and appropriately,” the law firm Payne Hicks Beach said in a statement.

The 64-year-old rocker and 38-year-old anti-land mine campaigner announced their separation in May and have begun divorce proceedings in an increasingly acrimonious split. They have a 3-year-old daughter, Beatrice.

Why in the world would a billionaire get married without a pre-nup?  Looks like Heather Mills will make her fortune the old-fashioned way – through divorce.
