Heard’s hunky stuntman

THE muscular mystery man seen on video engaging in an epic makeout session with

Amber Heard in Australia in September is hunky stuntman Mana Hira Davis, Page Six can exclusively reveal.

Heard, who is on the Gold Coast finishing up “Aquaman” with Jason Momoa, was caught on video passionately kissing Davis in the backyard of her rental house by a guest at a real estate open house next door.

Davis (inset), who hails from New Zealand, has performed stunts in “San Andreas,” “Kingsman: The Secret Service” and “Ghost in the Shell.” He has also served as the stunt double for Richard

Armitage in the “Hobbit” films. According to his résumé, Davis is 6-foot-2, and can do high falls, harness and wire work, weaponry and swordplay, fight choreography and basic horseback riding. He is also a licensed personal trainer, forklift driver, open-water advanced diver, and is certified in CPR. He’s a serious upgrade from Heard’s ex-husband

Johnny Depp, whose stunts seem limited to emptying bottles of red wine and blasting Hunter S. Thompson’s ashes into space from a cannon.

Heard and Davis seem to be inseparable, according to sources. The new couple was spotted last week with Heard’s best friend Raquel

Pennington and stuntman Kelly McNaught at Harajuku Gyoza Beer Stadium in Broadbeach, Queensland. Heard previously dated tech billionaire Elon Musk, but the couple split in August, partly due to their busy schedules. “Although Amber and I did break up, we are still friends, remain close and love one another,” Musk wrote on Instagram.“Long distance relationships when both partners have intense work obligations are always difficult, but who knows what the future holds.” A rep for Heard did not respond. Davis’ rep tells us they “can neither confirm nor deny this rumor.”
