An unhinged Amber Heard screamed at Johnny Depp that he was “fat” and “washed up” when she attacked him on his private island, a UK court was told Tuesday.

Heard was a “thrower” — “someone who threw projectiles” — and would “lunge violently at Johnny, pull his hair, and commit other aggressive physical acts against him,” Roberts said in a witness statement in Depp’s libel case against The Sun newspaper.

Roberts detailed how Heard “repeatedly berated [Depp] with increasing ferocity” during one alleged assault in December 2015 when the couple was on the Caribbean island with Depp’s two children and a friend.

“She was insulting him, calling him names, and in the middle of this onslaught I heard her say specifically ‘your career is over,’ ‘no one is going to hire you,’ ‘you’re washed up,’ ‘fat,’ ‘you will die a lonely man,’ and also screaming things that were incomprehensible,” Roberts said.

Depp tried to leave — telling her to “just leave me alone!” — but his wife’s “screaming and berating rose to a fever pitch,” Roberts said.

“During this entire incident, I never saw Johnny hit Amber, or push her back, nor did he physically react to the attacks,” Roberts insisted.

“Amber, Johnny then told me, had thrown a quart-sized can of lacquer thinner into Johnny’s face, causing a gash,” her witness statement said.

The next morning, the bushes around their house were littered with art supplies — and Heard asked for help finding her wedding ring, which she had taken off and thrown during the fight, Roberts said.

Roberts insisted she never saw Depp being “violent or aggressive” with anyone.

Roberts also said that when Depp came to the island in August 2014 to detox from pain meds, there was “no discord” or anything “out of the ordinary,” despite Heard claiming that the actor flipped out and kicked her.

Prior to the couple’s marriage, Depp was “outgoing, friendly and social,” but there was a “distinct change” after his marriage, Roberts claimed.

“The once social and animated person spent most days sleeping, became withdrawn,” she said in her statement.

On the witness stand, Roberts insisted she “was not lying” in the statement to save her job, saying she had other sources of income.

“Correct,” Roberts told the court.
