Last week, 20th Century Fox unleashed the mother of all collaborations – a music video featuring Deadpool and Celiné Dion to promote Deadpool 2.

Not content with letting Fox take all the glory when it comes to bizarre pop team-ups, Warner Bros. has now thrown down the gauntlet (and cast a healthy dose of shade) with its own slice of pop absurdity to promote Teen Titans GO! to the Movies.

Yep, they’ve brought out the big guns – they’ve brought out Michael Bolton!

Taking to social media, Warner Bros. Pictures posted the following video, with the accompanying caption: “Hey, Deadpool movie. We see your Celine Dion and raise you a Michael Bolton!”

When will this insanity end?
