In 2011, George Michael joined James Corden for a BBC Comic Relief sketch which went on to inspire the viral hit Carpool Karaoke from Corden's Late Late Show on CBS.
Corden tweeted on Saturday: "I've loved George Michael for as long as I can remember. He was an absolute inspiration. Always ahead of his time."
