Musician Sir Elton John and his partner David Furnish have formally converted their civil partnership to a marriage, according to a post on the Instagram social network.
Sir Elton posted: “That’s the legal bit done. Now on to the ceremony.”
The couple will host a ceremony at their Windsor estate in Berkshire later and a number of stars are expected to attend, a spokesman said.
Sir Elton and Mr Furnish tied the knot in a civil partnership in 2005.
In March, the law was changed in England and Wales to allow same-sex marriage.
Sir Elton said at the time he was “very proud” of Britain for changing the law.
“Having our civil partnership was an incredible breakthrough for people that have campaigned for a long time – through the 60s and the 50s in England when it was so hard to be gay and hard to be open about it. And it was a criminal act.
“So for this legislation to come through is joyous, and we should celebrate it. We shouldn’t just say, ‘Oh, well we have a civil partnership. We’re not going to bother to get married’. We will get married.”
Sir Elton had already posted a number of pictures to the photo-sharing website, where he has thousands of followers, including a picture taken at a window showing a garden, with the caption: “Good morning! Nice day for a wedding. #ShareTheLove”.
He also posted a picture of a wedding invitation.
The couple have two sons, Zachary who was born in 2010 and Elijah, born last year.
On 21 December 2005, they held a civil partnership ceremony at the Windsor Guildhall.
Victoria Beckham, Helena Bonham Carter and Sir Michael Caine were among guests at a star-studded reception
