London, Dec 22 - Sir Elton John has finally tied the knot with his long- time gay partner David Furnish at a ceremony at their Windsor estate in Berkshire, England.

The 67-year-old singer shared photographs on his Instagram account with a caption "It's beginning!! The Registrar welcomes our guests. #ShareTheLove", the BBC reported.

David Beckham, Victoria Beckham, musician Ed Sheeran, actor David Walliams, Burberry chief executive Christopher Bailey and comedian Jimmy Carry were among the guests at the wedding.

John and Furnish, who have two sons, became civil partners in 2005 and decided to tie the knot after gay marriage became legal in England.

The Brit singer posted a number of pictures to the photo-sharing website. (ANI)
