Amber Heard has confirmed she will be taking on the role of Mera, the love interest of Aquaman, in the action-packed Justice League films.

The 29-year-old announced the exciting news to Entertainment Tonight, and will also be appearing in the standalone Aquaman film with Jason Momoa in the title role.

Speaking about her costume for the underwater queen, Amber said: 'It’s interesting. It’s like, half suit of armor, half scales. It’s strange… We’re in the process of building it now, so it’s coming along.'
