Elon Musk is living it up on a yacht in Greece.

The 51-year-old billionaire was photographed swimming with his shirt off.

He was accompanied by fashion designer Sarah Staudinger, 33.

Her husband, agent Ari Emanuel, 61, was also with them.

The Internet had a lot of reactions to photos of him going shirtless.

“A warning would be nice before you posted this picture,” one user wrote.

“My first thought was he can not be that white,” another commented.

“He needs to get out in the sun more often,” another user said.

They added, “He's practically Casper the friendly ghost.”
