Elon Musk is out in these streets bragging about how Amber Heard made a sexy 'Overwatch' cosplay for him

• Elon Musk bragged on X about the sexy "Overwatch" cosplay Amber Heard made for him. 
• Musk told Heard she reminded him of Mercy, his favorite character from the game, according to a new biography.
• Heard then spent two months designing the cosplay so she could role-play for him, the book reported.

Elon Musk gloated on X — the social media platform he owns — about how ex-girlfriend Amber Heard once made a sexy "Overwatch" cosplay outfit for him.

According to a new biography about Musk written by Walter Isaacson, Musk once told Heard — whom he dated in 2016 — that she resembled Mercy, the billionaire's favorite character in the video game "Overwatch."

That comparison motivated Heard to spend two months "designing and commissioning a head-to-toe costume so she could role-play for him," per Isaacson's book.

And it didn't take Musk very long to show up on X with photographic proof of the outfit. On Wednesday, he shared an image of Heard in a considerably skimpier version of the character's official outfit.

Musk dated Heard after they met at the 2016 Met Gala and during her high-profile divorce from actor Johnny Depp.

Heard confirmed their relationship in an April 2017 Instagram post. She then wrote about their breakup several months later in another Instagram post in August 2017.

The couple then got back together before breaking up again in February 2018, according to People.

It's worth noting as well that the Isaacson biography paints Heard in a fairly unflattering light. In several parts of the book, Heard is described as being hated "with a passion" by Musk's brother and his friends.

Grimes — who also dated Musk and shares three children with him — also described Heard as being the "chaotic evil" to her own "chaotic good."

"She was like the Joker in Batman," Musk's chief of staff, Sam Teller, told Isaacson. "She didn't have a goal or aim other than chaos. She thrives on destabilizing everything."

Representatives for Heard did not immediately respond to Insider's request for comment.
