They’ve been rumoured to be dating since mid-2016, but Amber Heard and tech entrepreneur Elon Musk only just made their relationship Instagram official.

After being spotted together on the Gold Coast, where Amber is based to film Aquaman, both the actress and the billionaire shared a loved-up photo to Instagram at the same time. The photos are similar, showing Amber with her arm resting on Elon’s shoulder, and some of her lipstick rubbed off on his cheek.

The pair did a service to Moo-Moo Restaurant, with Musk tagging their dinner location in the post; the venue can expect an influx of reservations thanks to the couple’s combined 1.5 million Instagram followers.

Musk, 45, who finalised his divorce from British actress Talulah Riley last year, is a prolific tech entrepreneur. The CEO of electric car company Tesla and aerospace manufacturer SpaceX, Musk is estimated to have a net worth of almost $14 billion, making him the 80th richest person on earth.

Amber, 30, is no doubt pleased to be making some happy memories on the Gold Coast. In 2015, she and ex-husband Johnny Depp were at the centre of a furore when it was revealed they brought their dogs Pistol and Boo into Australia on a private jet without declaring them to customs officials. After a court appearance last year, they agreed to film an awkward apology video about Australia’s delicate ecosystem.
