Congratulations, Elton John and David Furnish!

The longtime partners married at their Windsor home in England on Sunday, Dec. 21 — and the newlyweds shared many of their wedding details on social media!

Early that morning, Elton, 67, took to his Instagram page to share a photo of him and David, 52 — his partner of 21 years — signing their marriage license prior to their intimate afternoon ceremony.

"That's the legal bit done. Now on to the ceremony! #ShareTheLove," the caption read.

The couple then shared a sweet snapshot of them exchanging vows in front of guests including Elizabeth Hurley, David and Victoria Beckham, and Ozzy and Sharon Osbourne, just to name a few.

The pair began dating in 1993 and were among Britain's first same-sex couples to tie the knot when civil partnerships became legal in 2005.

The Dec. 21 wedding — in which the couple converted their partnership into a legal marriage — took place on the nine-year anniversary of their civil ceremony.
