Paul McCartney and his blushing bride-to-be are set to walk down the aisle this coming weekend. The former Beatle and Nancy Shevell will exchange their vows at his farmhouse located in Sussex, England.

"It will be a small, intimate wedding," a source tells Us Weekly. "It's going to be very elegant and classic."

"They will be marrying imminently," another source tells UK's Daily Mirror newspaper. "They are very excited and almost everything is in place. Friends and family have been put on standby."

The couple are supposedly planning a second celebration back in the U.S., on Shevell's home turf of Manhattan. "They are having a big party in New York to celebrate later on," the source reveals.

McCartney's marriage to Shevell will mark the third time he has said "I do." McCartney, 69, was first married to Linda (née Eastman), who died in 1998 at the age of 56 after her battle with cancer. The two were married for 30 years and have three children together. His second marriage to Heather Mills in 2002 came to a bitter end after six years.

McCartney announced his engagement to Shevell, 51, in May. The singer popped the question to Shevell, a businesswoman New York City, in April with an engagement ring valued at a whopping $650,000.
