Billionaire Elon Musk posted photos on Twitter of himself in a samurai costume at a Halloween party with his mother.

The richest man on the planet posted the photos on Tuesday morning along with the message: “Halloween with mom.”

In two photos published by Twitter, Musk appears in a red samurai-style suit. In one of the pictures, he is with his mother and German model Heidi Klum, whose party he attended, the Daily Mail reports. In the second photo, the billionaire appears alone, getting out of the car.

According to the website of luxury costume shop Abracadabra NYC, Musk’s outfit is the Devil’s Champion-Leather Armor set, which retails for $7,500, the Daily Mail notes.

We remind you that over the weekend, most of the Romanian mass media wrote that Musk would be at a Halloween party in Bran Castle, the information turned out to be false. Lia Doru-Trandafir, the administrator of Bran Castle, told Cotidianul that Elon Musk did not come to Romania.

On Sunday evening, Bran Castle hosted a lavish party attended by billionaires Peter Thiel, the founder of PayPal, and his partner Mat Dantzeisen, as well as Hollywood actors such as Adrian Grenier, who strolled through the center of Brasov over the weekend.

Among the guests at the castle was the mayor of Bran, Ioan-Cosmin Feroyu.

“I had the honor of being invited to a private party where there were about 200 people in costumes and masks. I can’t tell you for sure if Elon Musk was there or not. I didn’t see him in person, but he didn’t. It doesn’t mean , that he could not be under a certain mask. But I did not meet him,” Mayor Branu told HotNews.ro.
