Amber Heard said she has been working hard to prepare for her role as Queen Of The Atlantis Mera in Aquaman.

And on Thursday the 31-year-old actress finally shared an image from the set of the 2018 film that also stars Jason Momoa.

‘Over a year of prep, 6 months of training, & countless hrs of denying myself pleasure, aka donuts, has led to this moment: Day 1,’ the ex-wife of Johnny Depp wrote.

The star had a scarf on her head and her feet were up as a makeup artist applied lipstick to the beauty. In her hand was an Aquaman comic book.

The character of Mera will make her debut in the movie Justice League, out this November.

Her role in Justice League will be a supporting one, and she will take a much larger part in Aquaman, which is slated for release on December 21, 2018.

On Tuesday, the former Mrs. Depp gave fans some insight into her training routine for the upcoming blockbuster.

In a time-warped video, Heard can be seen doing a series of yoga moves with a trainer.

She wrote ‘Thank you @fitnessbyfortitude for making a few hours a day feel like just minutes.’

Amber has been Down Under since April 19 when she posted a photo of herself with the caption ‘Hello Brisbane! #aquaman.’

Days prior she attended the Unite For Humanity Gala in Los Angeles, but left the event early for a ‘medical emergency.’

‘I wish I could have stayed for the entire event,’ she wrote to fans after news broke of her early exit from the gala.

In love: The ex of Johnny Depp is now dating Tesla founder Elon Musk, as seen in this photo she shared to Instagram

Amber is currently dating 45-year-old Tesla founder Elon Musk, who is said to have wooed her with one of his brand’s vehicles.

She was married to her The Rum Diary co-star Johnny Depp from 2014 until 2016, when they divorced after accusations of abuse.

Ironically it was in Australia, where Amber is filming Aquaman, where she and Depp were cited with illegal dog smuggling as he filmed the fifth Pirates Of The Caribbean movie, and were forced to issue a public apology.
