Justin Bieber Challenged Tom Cruise To An MMA Fight For Some Reason

It's the year 2019 and Justin Bieber has challenged Tom Cruise to a duel.

"I wanna challenge Tom Cruise to a fight in the Octagon," Bieber casually wrote on Twitter.

"Tom if you dont take this fight your (sic) scared and you will never live it down," he added, tagging Dana White -- president of the UFC -- in his quest to find a venue for the match-up.

We're not too sure what Cruise might have done to earn the invitation but perhaps Bieber wasn't a fan of the latest 'Mission: Impossible' film?

Cruise famously performs most of his own stunts and has undergone extensive physical training throughout his 30-year career on the silver screen.

He knows how to wrestle, fly a helicopter, use a range of firearms, scale tall buildings, parachute out of planes, hold his breath underwater for six minutes and has been trained in the art of Krav Maga.

The action star's well-known CV has led the internet to collectively ask, 'Why on earth would anyone want to fight Tom Cruise?'

To make things even weirder, UFC World Champion Conor McGregor has piped up on Twitter, offering to host any potential bout between the 25-year-old "Despacito" singer and the 56-year-old action star.

Cruise isn't particularly active on social media, last posting on Twitter back in January to promote his latest film -- so we might not hear his response to Bieber's invitation any time soon.

Unfortunately, as McGregor tweeted, we're going to have to "stay tuned" to this mess to find out.
