The comments thread of Amber Heard's post is filled with responses calling the actress a 'gold-digger' and variations of the same theme - a repeat of the accusation that was levelled against her during the acrimonious divorce from Johnny Depp.
Elon Musk's post has similar comments advising him (rather prematurely) to consider a prenup. The Tesla and SpaceX founder has been married twice - his second wife is actress Tallulah Riley.
Amber Heard met Johnny Depp when they were filming 2011's The Rum Diary. They married in 2015 and split up in 2016 amid allegations by Amber that she had been physically assaulted by Johnny, which he denied. Called a gold-digger by several of Johnny's friends and much of social media, Amber Heard announced she would be donating her divorce settlement - roughly $7 million - to charity.
Amber Heard, star of films such as Never Back Down and Drive Why, has been cast as Mera, queen of Atlantis and wife of Aquaman, in the upcoming DC Films' series. She makes her first appearance as Mera in November release Justice League and later in the standalone Aquaman film opposite Jason Momoa.
