Depp pal: It’s an Amber alert

ONE of Johnny Depp’s closest friends believes Amber Heard is “a sociopathic show pony” who is hell-bent on destroying the star.

Gina Deuters — who has known Depp for nearly 20 years — had a front-row seat to his tempestuous 15-month marriage with Heard, and alleged that he is actually the real victim of domestic abuse.

In her only interview since being stripped from the witness stand — she was dramatically kicked out of the courtroom after admitting she’d seen clips of the vitriolic trial online — Deuters described Depp’s time with Heard as “less of a relationship and more of an Amber invasion.”

British-born Deuters, the wife of Depp’s longtime business partner and assistant Stephen Deuters, exclusively told Page Six she believes Heard thrives on drama.

Deuters explained, “There was one thing she said at the wedding . . . ‘Do you and Stephen ever fight?’ I responded that we sometimes have an argument, and she was like, ‘No Gina, like really fight?’ And it was kind of unnerving. [I thought], ‘Do you enjoy it?’ ” she recalled.

“This is my opinion — but I think there is a part of Amber that [believes] fighting is passion, it means there’s sparks, fireworks . . . there’s passion [in the relationship].”

Deuters continued, “[Amber] is someone who is always used to getting what she wants — she is quite entitled and I think that she made big demands in their divorce.

“When she was denied those demands, I feel she was like, ‘I am not going to get what I want so I am going to destroy you.’ ” Deuters added that her husband called Heard “a sociopathic show pony” when he became the mediator in Depp and Heard’s marriage in its final difficult days.

“My husband . . . called her a sociopathic show pony, and he certainly doesn’t regret it . . . Stephen, at the end, was quite literally the mediator . . . no one else wanted to deal with Amber, and Stephen would be the only person she could talk to.”

A rep for Heard declined to comment.
