Sir Paul McCartney will no longer be a bachelor anymore on Sunday.
McCartney will wed U.S. heiress Nancy Shevell in a civil ceremony in London, according to British media reports.
McCartney, 69, and Shevell, 51, got engaged in May.
They will exchange vows at the Westminster Register Office in London in front of only 30 guests, The Daily Mirror reported.
The ceremony will be followed by a reception in McCartney’s garden, where a tent has been set up.
McCartney’s daughter, designer Stella McCartney, designed Shevell’s dress, according to the Sun.
“The wedding is in keeping with the way Paul and Nancy have conducted their entire relationship – low-key, understated and fueled by goodwill. Neither of them wanted a huge fuss made and the main priority, for both, was family,” said a source close to the star, the Daily Mirror reported.
“It will be a really special, intimate ceremony followed by a fun do under a marquee in the garden. They have chosen a fairly spectacular wedding cake, and ordered a chocolate one for the younger guests. Paul’s daughter, Stella, was instrumental in helping choose an entirely vegetarian, mostly organic, three-course sit-down meal,” the source added.
The couple is expected to honeymoon in the Caribbean later this month.
This will be McCartney’s third marriage.
He married the late Linda Eastman in 1969, who died of breast cancer in 1998.
Four years later, he married former model Heather Mills, but it ended in a bitter split in 2006.
McCartney was introduced to Shevell by mutual friends a year later.
For the most part, the couple has kept their relationship private.
They did appear together in public, however, for the premiere of the former Beatle’s new ballet, Ocean’s Kingdom, at the New York City Ballet’s 2011 Fall Gala, according to multiple reports.
It is the first time McCartney has written an orchestral score for dance. The ballet will be released as an album in October 2012.
