Elon Musk is on vacation!

The Tesla and SpaceX CEO, 51, was spotted relaxing on a luxury yacht moored off the coast of Mykonos, Greece, on Sunday.

Keeping things casual in a plain T-shirt and swim shorts, Musk appeared to be kicking back with friends following the termination of his deal to purchase Twitter, for which Twitter is suing him, and a feud with former President Donald Trump.

Musk’s new spat with Trump, 76, started during a July 9 political rally in Alaska, when Trump spoke about the billionaire’s claim that he’d recently voted for a Republican for the first time, according to The Washington Post.

“He said the other day, ‘Oh, I’ve never voted for a Republican.’ I said, ‘I didn’t know that,’” Trump said at the rally. “He told me he voted for me, so he’s another bull— artist.”

Musk responded to Trump’s criticism via Twitter in a reply to a Breitbart News tweet that shared Trump’s comments.

“I don’t hate the man, but it’s time for Trump to hang up his hat & sail into the sunset,” wrote Musk. “Dems should also call off the attack – don’t make it so that Trump’s only way to survive is to regain the Presidency.”

Trump replied on Truth Social that Musk “should focus on getting himself out of the Twitter mess because he could owe $44 billion for something that’s perhaps worthless.”

In a further post, Trump mulled about why Musk was “allowed to break the $15 million stock purchase barrier on Twitter without any reporting?”
