Justin Bieber seems to be punching above his weight, challenging prolific actor Tom Cruise to a UFC fight for reasons no one can quite pin down.

After more than 10 years in the game, the general public would be aware by now that Justin Bieber is a rather enigmatic character.

After all, with such high levels of fame and fortune at such an early age, we’re surprised he hasn’t taken the Macaulay Culkin route at this point and become something of a recluse (or a meme).

However, Justin Bieber has completely upped the ante in terms of bizarre behaviour, taking to Twitter recently to challenge Tom Cruise to a fight for reasons that are still completely unknown.

I wanna challenge Tom Cruise to fight in the octagon. Tom if you dont take this fight your scared and you will never live it down. Who is willing to put on the fight? @danawhite ? — Justin Bieber (@justinbieber) June 10, 2019

If Tom Cruise is man enough to accept this challenge,

McGregor Sports and Entertainment will host the bout.

Does Cruise have the sprouts to fight, like he does in the movies?

“I wanna challenge Tom Cruise to fight in the octagon,” Justin Bieber wrote on Twitter recently. “Tom if you dont take this fight your [sic] scared and you will never live it down.

“Who is willing to put on the fight?” Bieber asked, before tagging in Ultimate Fighting Championship president Dana White.

Of course, the question on everyone’s lips right now is, well, “why?”

What has Tom Cruise done to raise the ire of the Biebs, so much so that a bout of mixed martial arts is the only way to reconcile their differences?

While plenty of people are questioning the reason behind the proposal, and whether or not Cruise will take Justin Bieber up on his offer, the pop star appears to be having fun with the whole situation, sharing a fan-made parody of Cruise in the 1992 film Far and Away, with Bieber added in as his foe.

“If Tom Cruise is man enough to accept this challenge, McGregor Sports and Entertainment will host the bout,” noted UFC champion Conor McGregor later shared on Twitter. “Does Cruise have the sprouts to fight, like he does in the movies? Stay tuned to find out!”

In related news, it was revealed that an influx of Justin Bieber fans had caused the closure of an Icelandic canyon, after the pop star featured the location in a music video.

“Rash behaviour by one famous person can dramatically impact an entire area if the mass follows,” Environment minister Guðmundur Ingi Guðbrandsson said.

“In Justin Bieber’s defence, the canyon did not – at the time he visited – have rope fences and designated paths to show what was allowed and what was not.”

While Iceland’s ecosystem is rather fragile to begin with, a 20% annual rise in visitors has led to widespread soil erosion in its volcanic areas, resulting in a closure that was extended until the 1st of June.
