Everyone welcome to the stage: James Corden's Thank u, Jeff.
He's even perfectly recreated the Mean Girls scenes of Grande's epic rom-com music video - complete with a Jeff burn book, a Christmas concert dance sequence and a scene involving Corden in silk pyjamas as he professes his admiration for Goldblum. "Then he won independence from an alien mess", Corden sang, referring to "Independence Day". "In Thor: Ragnarok, his performance was classic".
Ariana Grande saw the video and was immediately drawn to the book. There was also a healthy amount of simple flattery, "he's our silver fox with black thick-rimmed glasses. The way that he talks will charm off your asses". "It's for a friend, promise".
"That journal with all the pictures of me... have you had that for a while?"
"No... I'll get rid of it", Corden says bashfully.
Grande's "Thank U, Next" music video was released last week and has already broken records on YouTube.
