Singer Elton John has officially married his long-time partner David Furnish.

The singer also created an account on Instagram to document his big day.

Dressed in a navy suit with matching shirt, the "Tiny dancer" hitmaker sat alongside Furnish as they signed papers Sunday, reports mirror.co.uk.

John captioned the snap: "That's the legal bit done. Now on to the ceremony! #ShareTheLove @DavidFurnish"

The couple are expected to carry on celebrations in their Windsor residence, with their two sons Zachary and Elijah playing a major part in the "small and intimate" bash.

John had earlier shared a photo of two pairs of shoes placed in front of the fire.

He said: "Our little ring bearers are fast asleep, and their shoes are polished and ready for tomorrow's (Sunday) celebration. @DavidFurnish #ShareTheLove"

The duo have been together for over 20 years and exchanged vows for a civil partnership back in 2005.
