Billionaire Elon Musk has changed his name on Twitter to "Elona Musk" after a cheeky exchange with Ramzan Kadyrov, the President of the Chechen Republic.
Earlier this week, Musk hit the headlines after challenging Russian President Vladimir Putin to a "single combat".
In a statement on Telegram, shared by the Tesla and Space X CEO, the Chechen leader warned Musk to be careful of what he was asking for.
