Mark Zuckerberg has earned a blue belt in Jiu-Jitsu ahead of his fight with Twitter CEO, Elon Musk.
The billionaire is preparing for potential fight with his fellow billionaire social media rival, Musk.
The Meta boss, 39, posted images to his own Instagram platform over the weekend showing off his new jiu-jitsu blue belt, as he was presented with a certificate by his colleagues.
Writing on Instagram, Zuckerberg first praised his jiu-jitsu coach for becoming a black belt, before addressing his own promotion.
'Congrats @davecamarillo on your 5th degree black belt,' he said. 'You're a great coach and I've learned so much about fighting and life from training with you. Also honored to be promoted to compete at blue belt for @guerrillajjsanjose team.'
It is still unclear whether Musk and Zuckerberg will follow through on their promise to do battle in the ring though both of them have trained rigorously.
