The two lovebirds were pictured sitting at a dinner table while Amber placed her hand on her beau's shoulder.
A lipstick kiss mark is clearly visible on his cheek.
The "Aquaman" actress simply captions it with "Cheeky." Elon posted a similar photo and wrote in the caption, "Having moo moo at Moo Moo Gold Coast with @AmberHeard, @CreepyPuppet and @CowanFilms."
The new lovers spent time together this weekend in Australia, where Amber has been filming her new movie "Aquaman".
Amber and Elon were first rumoured dating in July 2016, after she filed for divorce from Johnny Depp.
