The US chat show host and bona fide rock legend are seen singing along to some of Rod's biggest hits as they drive through LA, including the classics 'The First Cut Is The Deepest' and 'Maggie May'.
Elsewhere, A$AP Rocky jumps in for an impromptu rendition of 'Everyday' in between Rod talking about his 'drinking and shagging' days.
But our absolute favourite moment is Rod's EXTREMELY camp version of 'Do You Think I'm Sexy?'.
What. A. Legend.
Previous stars to have been taken for a ride around the block by James include Justin Bieber, Mariah Carey and Jennifer Hudson, who had us in stitches when they pulled up to a drive-thru window and she belted her order at a fast food worker.
