Mega-billionaire social media bosses Mark Zuckerberg and Elon Musk have a history of taking shots at each other in the press.

Things may be about to get physical.

Yesterday, in response to a report that Meta was building a competitor to Musk's Twitter, Elon quipped that he was ready to get in a cage with Zuckerberg.

Zuck caught wind of that and asked for the addy.

Zuckerberg is a martial arts enthusiast who recently won his first amateur Brazilian jiu-jitsu tournament.

Elon vs. Zuck, who you got?
