Could the Tacoma Dome play host to a fight between Justin Bieber and Tom Cruise

Cape Town - Justin Bieber has challenged Tom Cruise to a fight. "Tom if you don't take this fight your scared and you will never live it down", the Biebs tweeted, calling on UFC president Dana White to help make it happen.

"It was just a random tweet", he said with a smile in a video published on TMZ.

We will never know the series of thoughts that led to this decision, all we know is that Bieber came to the conclusion that he simply must engage in hand-to-hand mixed martial art combat with Cruise in the octagon.

It turns out Justin Bieber doesn't actually want to fight Tom Cruise - because he knows the Mission: Impossible star would probably win. Who's willing to put on the fight?

The musician's tweet immediately caught the attention of Ultimate Fighting Championship (UFC) fighter Conor Mcgregor, who approved of the bout and even offered his company's services in hosting the clash.

"He's got that dad strength", he continued, before asking, "He's a dad right?"

The Irish sportsman questioned Cruise's fighting skills, adding: "Does Cruise have the sprouts to fight, like he does in the movies?"

"Stay tuned to find out!" the Irishman said.

The Irish athlete, 30, then called on Mark Wahlberg to compete against him in a fight of their own.

"I challenge Mark Wahlberg on the very same card".

The 25-year-old singer tweeted Sunday that he wanted to battle against the 56-year-old actor in what appeared to be a joking taunt.
