Sir Elton John and David Furnish have officially married - nine years to the day they tied the knot in a civil partnership ceremony.
In his first post on his newly-created Instagram account, Sir Elton put up an invitation requesting "the pleasure of your company" and said the couple would share "special moments from our big day".
On Sunday morning, he posted a photo of himself, pen in hand, sitting next to Furnish with the message: "That's the legal bit done. Now on to the ceremony!"
The Beckhams and Elizabeth Hurley were among the high-profile guests at the ceremony at the couple's mansion in Old Windsor, Berkshire.
Hurley tweeted a picture of herself with her son, saying: "On our way to Elton and David's wedding. V excited."
Sir Elton later posted a picture of the ceremony, showing the registrar welcoming guests.
She is seen standing in front of a Damien Hirst work called The Incomplete Truth - a dove suspended mid-flight in formaldehyde.
The wedding menu was wild mushroom soup with truffle cream, followed by beef short rib and caramelised onion pie, warm chocolate pudding and wedding cake.
The light lunch was washed down with Pouilly Fumé Baron de 'L' 2009 and Laurent-Perrier Rose wines.
Before the ceremony, Sir Elton posted an image of their two sons' shoes, with the message: "Our little ring bearers are fast asleep, and their shoes are polished and ready."
The 67-year-old singer and Canadian-born filmmaker tied the knot in a star-studded civil partnership ceremony at Windsor Guildhall on 21 December, 2005.
Earlier this year, Sir Elton told Sky News why it was important for him and Furnish to marry now it was legal.
"We had our big shebang when we had our civil union, but we will (have a wedding).
"I think it's a great opportunity to take advantage of the new laws and to celebrate," he said.
"We're very lucky in this country to be able to have that advantage and to have that position to be in."
