Pop sensation Justin Bieber has challenged Hollywood legend Tom Cruise to a fight "in the Octagon" overnight.
Tweeting in the late evening on Sunday, Bieber wrote: "I wanna challenge Tom Cruise to fight in the octagon. Tom if you don't take this fight your scared and you will never live it down. Who is willing to put on the fight?"
Bieber also tagged UFC President Dana White in the tweet, confirming that he wants to do things MMA-style. It is unclear whether Bieber or Cruise have any MMA training whatsoever.
Neither Cruise nor White have responded to Bieber's request.
