Sir Paul McCartney and Nancy Shevell engaged

Sir Paul McCartney is to marry for a third time following his engagement to New Yorker, Nancy Shevell.

The 68-year-old former Beatle is said to be ‘ecstatic’ about the announcement to the 51-year-old, whom he has dated for four years. According to the Daily Mail, the couple are due to marry this summer but the wedding reception venue is yet to be decided.

Curiously, the couple are not signing a pre-nuptial agreement. McCartney, who is worth an estimated £495m, entered a bitter legal battle with ex-wife, Heather Mills, following their divorce in 2008. Ms Mills was awarded £24.3m after seeking a £125m settlement. She now has a career mainly based in the United States.

A source close to the couple, who announced their engagement on Friday told the Mail on Sunday: “Paul trusts Nancy implicitly. She is wealthy in her own right and certainly isn’t after him for his money.”

“There is no pre-nuptial agreement but Nancy told me they are having a simple one-page legal document drawn up, which she is more than happy to sign. It states that, in the event of a divorce, she will not make any claim on the trust funds of his children or grandchildren.”

McCartney’s first wife, Linda, died of cancer in 1998. She introduced the ‘Love Me Do’ singer to vegetarianism and animal rights activism. She was also in his former band, Wings.
