In addition to the requisite movie clips, the video has Celine singing onstage to an empty theater, with Deadpool doing some pretty amazing dance moves . . . in stiletto heels, no less. Obviously, it's not Ryan Reynolds.
But Ryan's Deadpool does make a cameo at the end, telling Celine they have to do another take . . . because she was TOO GOOD.
He says, quote, "This is 'Deadpool 2', not 'Titanic'. You're at, like, an 11. We need to get you down to a five, five and a half tops. Just phone it in."
Celine says, quote, "Listen, this thing only goes to 11. So beat it, Spider-Man!"
To which he replies, quote, "God, I should have asked 'N Sync."
