AMBER HEARD and billionaire Elon Musk stepped out together for the first time in public while in Australia, where the actress is currently filming her upcoming movie “Aquaman.”

The actress, 31, and the Tesla founder, 45, spent Sunday at the Gold Coast’s Currumbin Wildlife Sanctuary, where they walked arm-in-arm through the reserve. The pair also held hands and took part in the sanctuary’s TreeTop Challenge zip lining ropes courses.

Later on Sunday, Heard made the couple’s romance Instagram official by sharing a photo of herself resting her arm against Musk.

“Cheeky,” she captioned the photo.

This isn’t the first time Heard and Musk have spent time together. In March, both attended a VIP movie screening of Al Gore’s upcoming documentary, “An Inconvenient Sequel: Truth to Power in California.” The two were also spotted last July at the same luxurious Miami hotel, the Delano South Beach, though they were not seen together.

Heard’s contentious divorce from actor Johnny Depp was finalized in January; Heard officially filed for the split last May. Musk filed for divorce from wife Talulah Riley in January 2015. Musk has five sons from a previous marriage.
