Heard is in Australia filming upcoming DC Comics flick Aquaman, and Musk has come down for a surprise visit.
On Sunday they went ziplining through trees at Currumbin Wildlife Sanctuary on the Gold Coast, like the lovebirds they are.
Then they went to dinner with the film's director, James Wan, and executive producer, Rob Cowan, at local restaurant, Moo Moo.
If you've ever scrolled through his feed, Musk's Instagram is primarily populated with Tesla and SpaceX stuff, and little about his personal life.
