Later in the evening, Heard snapped a photo of herself and Musk dining at a restaurant, after she'd planted a kiss on the Tesla Motors CEO's cheek.
Musk shared a similar snapshot, which he captioned, "Having moo moo at Moo Moo Gold Coast with @AmberHeard."
Musk and Heard were first romantically linked several months ago, in late 2016, just a few months after Musk filed for divorce from ex-wife Talulah Riley, whom he was married to and divorced from twice. Heard's divorce from ex-husband Johnny Depp was finalized in January.
