Elon Musk, the billionaire entrepreneur and founder of SpaceX and Tesla, has revealed some details about his past relationship with actress Amber Heard. In a recent interview with Vanity Fair, Musk confirmed that he and Heard had a “great time” together and that they enjoyed dressing up as characters from video games and movies.

One of the costumes that Musk mentioned was Mercy, the angelic healer from the popular online game Overwatch. Musk said that Heard looked “awesome” as Mercy and that they had a lot of fun roleplaying as the game’s heroes. He also praised Heard’s acting skills and said that she was “very talented and smart”.

Musk and Heard dated for about a year, from 2016 to 2017, after meeting on the set of Machete Kills, a film in which they both had cameo appearances. They broke up amicably, citing their busy schedules and long distance as the main reasons. Musk said that he still considers Heard a friend and that he wishes her all the best.

Heard, who is best known for her roles in Aquaman and The Rum Diary, is currently embroiled in a legal battle with her ex-husband Johnny Depp, who accused her of domestic abuse and defamation. Heard has denied the allegations and countersued Depp for $100 million. The case is expected to go to trial next year.
