Amber Heard hit by rumours she's been 'fired from Aquaman 2' after petition hits 1.8 million

Amber Heard has been hit with rumours she's been fired from Aquaman 2 and replaced by another famous actress.

The Rum Diaries star, 34, 'did not pass her physical examination' for the role and therefore 'violated' her contract, according to Australian website Sausage Roll and YouTube channel PopCorned Planet.

It comes as a Change.org petition to have Amber fired from the film has now been signed by 1.8 million people.

She is tipped to be replaced by Game Of Thrones actress Emilia Clarke.

A source told Sausage Roll: 'Amber Heard did not pass her physical examination.'

They added: 'There is a clause in her contract which says she is required to be in good form ahead of shooting and she violated that.'

Amber played Mera, wife of the DC Comics superhero Aquaman, in the first film.

Back in December, Forbes claimed Amber had been dropped from the sequel, with Emilia being lined-up to replace her.

Warner Bros. is yet to comment on the speculation publicly.

But Warner Bros. insider Daniel Richtman told We Got This Covered that the replacement rumour has 'no basis in truth'.

The Mirror has contacted reps for Amber Heard and Emilia Clarke, as well as Warner Bros. for comment.

Amber has been the subject of online abuse after her ex-husband Johnny Depp, 57, lost his libel case over an article in The Sun calling him a 'wife beater'.

Depp has denied he was abusive toward Amber and accused his ex-wife of being violent during their relationship, which Amber also denies.

The libel trial saw Johnny and Amber shed light on their relationship at London's High Court amid the backdrop of the ongoing pandemic.

Mr Justice Nicol ruled that Depp assaulted Amber on a dozen occasions and put her in 'fear for her life' three times.

The judge said The Sun calling the Pirates of the Caribbean actor a 'wife beater' was 'substantially true' according to the civil standard.

After the trial concluded, Johnny was asked to resign from his role in the third Fantastic Beasts film.

Depp is now challenging that ruling and his application for permission to appeal against it will be heard in March.

The actor claims he 'did not receive a fair trial' after the judge ruled against him.

Amber previously slammed the backlash over Aquaman 2, telling Entertainment Weekly : 'Paid rumours and paid campaigns on social media don't dictate [casting decisions] because they have no basis in reality.

'Only the fans actually made Aquaman and Aquaman 2 happen. I'm excited to get started next year.'
