Sir Paul McCartney ties the knot with US heiress Nancy Shevell

Sir Paul McCartney ex-Beatle has wedded US heiress Nancy Shevell at a ceremonial in London.

The couple posed for photo outside Old Marylebone Town Hall register office after being showered with confetti by wedding guests.

Ms. Shevell, 51, from New York, is an heiress to a haulage fortune.

She is Sir Paul's 3rd wife after Linda McCartney passed away in 1998 and he split from second wife Heather Mills during a spiteful divorce in 2008.

Ms. Shevell wore a white, long-sleeved costume and held a bouquet of roses, while the ex- Beatle wore a dark suit with a white shirt and pale blue tie for the event.

Several of fans congregated outside the central London register office to look the couple appearance and depart from their marriage ceremony, and blockades were upright.

A significant company of news reporters and photographers also waited for many hours before the newlyweds couple lastly come out.

The wedding gathering consumed more than an hour inside the place before rising on the steps of the building.

The couple then goes back to their home in St John's Wood for a welcome with family and close friends.

When asked who he thought after tying the knot for a third time, Sir Paul told waiting reporters: "Terrific, thank you. I feel married," adding, "I feel entirely magnificent."

Previous this month Ms Shevell enthused in with Sir Paul at his London home.

Ms. Shevell, who was wedded for 20 years to US lawyer and political candidate Bruce Blakeman, became engaged to Sir Paul in May.

The couple started dating four years before in the upmarket Hamptons area of Long Island.

Life-long Beatles fan Chiara Amato said she had sat outside the register office each day since September 29 in keenness of the couple's marriage.

She said: "This wedding is going to last. She looks like to be actually pleasant and profoundly in love with him. I have been taken notice to The Beatles since I was six-years-old. I have been to see Sir Paul in concert 27 times."

Sir Paul's eldest daughter, Mary, also wedded at the register office last year.

Ms Shevell is a board member of New York's carrying authority and vice-president of her family transport firm.

But the marriage is expected to indicate an end to her work in the family business and her exiting her position on the board of the transportation body.

Ms. Shevell told the New York Post she would "love" the couple to live in the America but she would "likely" move to England after the wedding.
