Robbie has announced he will be performing at this year's BBC Sports Personality of the Year show on 18 December.
He'll be providing the soundtrack to a very special event which celebrates the achievements of British Olympians and Paralympians at Rio 2016 and will take place at the Genting Arena in Birmingham from 18:40.
"I'm honoured to perform in such an iconic BBC programme," he said.
"It's been a truly amazing year for sport and I can't wait to take to the stage in Birmingham in front of such sporting heroes."
Laura Mvulva and Gareth Malone and the Invictus Choir will also sing during the show to a star-studded audience and millions watching at home on BBC One.
The last remaining tickets for the event are on sale now.
