Elon Musk is taking a trip down memory lane.

In a new biography on the SpaceX founder, Musk reflected on his yearlong on-again, off-again romance with Amber Heard.

But that’s not all, as biographer Walter Isaacson also revealed that the “Aquaman” actress once spent “two months designing and commissioning a head-to-toe costume so she could role-play” after he told her that she reminded him of his favorite video game character, Mercy from “Overwatch.”

Now, not only has Musk confirmed that was the case, sharing that “it was awesome,” the Tesla CEO also posted a throwback photo of Heard in her full “Overwatch” ensemble—which included a white bodysuit, mechanical wings and a gold halo headpiece—to X (formally known as Twitter) Sept. 13.

The pic from the past comes just days after the eponymous book was released, in which Heard, 37, also takes a look back at her relationship with Musk, 52.

“I guess I could be called a geek for someone who can also be called a hot chick,” she told Isaacson per Vanity Fair, noting that despite their split, she loves him “very much.”
