Justin Bieberis ready to throw some punches.

The “What Do You Mean?” singer had his fans asking just that after he challengedTom Cruiseto a UFC fight in a tweet Sunday.

“I wanna challengeTom Cruiseto fight in the octagon,” Bieber, 25, wrote. “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? @danawhite ?”

The UFC Octagon is the organization’s famed arena that features a plastic-coated fence surrounding all eight sides, while Dana White is the UFC president.

It’s unclear just what beef (if any) Bieber has with theTop Gunactor, 56, but Cruise is known for his athletic prowess, oftencompleting his own death-defying stuntson his film sets.

Bieber’s tweet quickly went viral, prompting UFC championConor McGregorto chime in with an offer to host the fight.

“IfTom Cruiseis man enough to accept this challenge, McGregor Sports and Entertainment will host the bout,” he wrote on Twitter. “Does Cruise have the sprouts to fight, like he does in the movies? Stay tuned to find out!”

The Irish athlete, 30, then called onMark Wahlbergto compete against him in a fight of their own.

“I challenge Mark Wahlberg on the very same card. Back when Mark Wahlberg was Marky Mark, I’d’ve still slapped the ears off him and took my UFC shares back,” hewrote.

Despite Bieber’s confidence, others weren’t so sure as to the likelihood of a victory, like the online sports betting company Odds Shark, whorespondedto his tweet with, “We don’t like your odds, Justin.”

Boxer Oscar De La Hoyaalso offered upGolden Boy Promotions, his combat sport promotional firm, to help get the fight going.
