But Sir Paul McCartney looked as excited and thrilled as if it was his first crack at marriage when he tied the knot with his American beauty Nancy Shevell.
Nancy, an American businesswoman – who looks considerably younger than 51 years – was radiant in a knee-length gown, adorned with a row of tiny buttons on the bodice, thought to be designed by his fashion designer daughter Stella.
She carried a small posy of flowers that matched his buttonhole. He wore a navy suit with a skinny blue tie.
They arrived hand-in-hand for the service, almost skipping up the steps of The Old Marylebone Town Hall the same venue in London, where he married his late wife Linda.
With them was Beatrice, his seven-year-old girl with ex-wife Heather Mills, who was the sole bridesmaid.
Around a dozen guests, including his five children – adopted daughter Heather, Linda’s daughter from a previous relationship, photographer Mary, Stella, musician James and Beatrice – were thought to be present.
As was her 19-year-old son, Arlen and his former Beatles bandmate Ringo Starr.
Outside the registry office where they became man and wife in a simple £1,540 ceremony, fans had congregated bearing balloons and banners.
Life-long Beatles fan Chiara Amato said she had sat outside the register office every day since September 29 in anticipation of the couple”s wedding.
She said: “This marriage is going to last. She seems to be really nice and deeply in love with him.
“I have been listening to The Beatles since I was six-years-old. I have been to see Sir Paul in concert 27 times.”
In contrast to his 1969 nuptials with Linda, which were hastily arranged the day before, Sir Paul and the new Lady McCartney announced their engagement a few months ago and posted notice of their intention to wed in September.
Sunday”s reception was due to took place at the address in St John”s Wood where the Beatle has lived for over 45 years.
Armfuls of delicate blush-coloured roses and white hydrangeas were delivered the day before. A marquee was erected and bottles of bubbly were chilling in a fridge in the garden.
Guests were expected to include Beatles film director Sam Taylor-Wood and her partner Aaron Johnson, Pink Floyd”s Dave Gilmour and his wife Polly Samson.
Sir Paul reportedly planned to serenade his elegant bride with Let it Be, which he sang to on one of their first holidays together three years ago.
Then he will perform her favourite, Let Me Roll It, and a third song he has written specially.
