As Mark Zuckerberg prepares for his famous mixed martial arts (MMA) fight with tech rival Elon Musk, he seems to be getting on his wife’s nerves according to a screenshot of their Whatsapp chat that he shared on his social media.

As UFC chief Dana White hopes to make the social media giants’ fight a reality, he said: “This would be the biggest fight ever in the history of the world, bigger than anything that’s ever been done. It would break all pay-per-view records.”

Upon being asked about the likeliness of the fight, White added: “Zuckerberg takes this very seriously, man.
