The "Rocket Man" star wed David Furnish on December 21, 2014 to embrace law changes in the UK which legalised gay marriage nearly a decade after the couple entered into a civil partnership in 2005.
John marked their first official wedding anniversary this week by posting a touching statement on Instagram, praising his longterm partner and insisting they are "happier than ever".
"Ten years ago... We were one of the first couples to embark on a Civil Partnership in the UK... One year ago... We renewed our lifetime pledge to each other by getting legally married. Today, we are happier than ever - and want to thank fans and friends for supporting us with such open hearts and joyful spirit.
