As The Blast first reported, Depp sued Heard for defamation over an op-ed Heard wrote last year where she referred to herself as "a public figure representing domestic abuse." Depp denies ever abusing Heard.
The lawsuit claims that shortly after their marriage, Heard began a relationship with Musk. "Unbeknownst to Mr. Depp, no later than one month after his marriage to Ms. Heard, she was spending time in a new relationship with Tesla and Space-X founder, Elon Musk," the documents state.
Depp claims Heard received many "late night" visits from Musk at Depp's residence and used the building's personnel to facilitate the visits. He claims the "Aquaman" star asked staff at the building to "give her ‘friend Elon’ access to the building’s parking garage and the penthouse elevator ‘late at night.’"
Depp's legal team claim they've deposed members from the building's security team, and they testified to seeing Musk leaving the building the next morning after his alleged late night visits.
As for what sparked the relationship between Heard and Musk, Depp claims the first time he noticed the Tesla CEO at his home was after an argument with Heard over entering into a postnuptial agreement. He claims that specific argument led to the actress allegedly hurling a vodka bottle at him in anger.
One of the main reasons Depp is bringing up Musk is to prove his case that Heard was lying about being abused by the "Pirates of the Caribbean" star.
He also claims Musk was given access to his home to spend the night with Heard on the same night she "presented her battered face to the public." They believe the entire claims of domestic abuse by Heard were an "elaborate hoax."
Heard and Musk were first linked in 2016 as they each went through public breakups (Musk filed for divorce again from "Westworld" actress Talulah Riley in 2015). They broke up in August 2017 and then got back together a few months later ... only to split again a few months after that.
In December 2018, Heard gave an interview with The Hollywood Reporter where she described her relationship with Musk by saying, "Elon and I had a beautiful relationship, and we have a beautiful friendship now."
Heard has not yet responded to Depp's $50 million lawsuit.
A rep for Musk tells The Blast, "Elon and Amber didn’t start seeing each other until May 2016, and even then it was infrequent. They were not on the same continent for most of this time. Their relationship didn’t become romantic until much later."
