Sir Paul McCartney is set to marry for the third time, tying the knot with American heiress Nancy Shevell in front of close family and friends.
It will be a trip down memory lane for the 69-year-old former Beatle, with the happy pair expected to exchange vows at The Old Marylebone Town Hall in London where he also married his first wife Linda.
A reception will be held afterwards at Sir Paul's house in nearby St John's Wood, where a marquee has been erected outside.
During the celebration the music legend is reportedly set to perform a collection of his own songs, serenading his new wife with special renditions of Beatles hit Let it Be and Let Me Roll It, as well as a new number he has penned especially for the occasion.
Shevell's dress has been designed by Sir Paul's daughter Stella, who also helped create a vegetarian, organic three-course meal, according to The Sunday Mirror.
All of the former Beatle's five children are also said to be attending the wedding, while his younger brother Mike is said to be his best man. Sir Paul is also expected to pay tribute to late wife Linda in his wedding speech, reports suggest.
A spokesman for Sir Paul said he could not comment on arrangements for the wedding, but on Saturday the singer/songwriter happily posed for photographs with his brunette fiancee outside the gates of his home.
Earlier in the day Shevell, who sits on the board of New York's Metropolitan Transportation Authority, looked happy and relaxed as she left the luxury pad in a pair of running shoes for a pre-wedding workout.
The pair then reportedly visited the nearby Liberal Jewish Synagogue where Shevell, who is Jewish, marked the end of Yom Kippur.
Last-minute preparations for the celebration were in full swing during the day with flowers and furniture seen being carried into the marquee outside Sir Paul's home.
