Who knew Justin Bieber wanted to really give Tom Cruise the hands? On Sunday, Bieber came out of nowhere, challenging Cruise to a fight in the Octagon, and reaching out to UFC president Dana White to gauge his interest in hosting their potential match. 

Bieber's challenge comes hours after the singer shared some uplifting news about new music on the horizon before declaring "Happy Sunday." 

If this whole situation sounds incredibly bizarre, you're not alone. There isn't a single reason to think that these two would ever step into the ring. But people are still running with Justin's suspected troll job. 

In the end, Bieber knows what his first priority should be. 

Conor McGregor apparently wants in on this, too. The maybe retired mixed martial artist tweeted that his company would be down to host the event if Cruise says yes.

Kevin Smith had some suggestions on how Bieber could best Cruise.

And Scooter Braun, the man who discovered Bieber, chimed in as well.
