Gary Barlow is to sing at Elton John's wedding to long term partner David Furnish.
Elton has left all of the organising to David and he's invited the Take That star to sing, reports the Mirror.
Gary said: 'I don't know what I'm going to sing yet. I don't think I'm going to write something, I'll perform something from the back catalogue.'
Elton hopes he and David can tie the knot at Windsor register office, where Prince Charles and Camilla got married, on December 21.
