King clean-cut.

“Aquaman” star Jason Momoa, 45, flaunted a clean-shaven look for the first time in six years as he prepares for his next role.

“God damn it, I hate it,” Momoa quipped in an Instagram reel posted on Wednesday.

The actor known for his role in “Game of Thrones” has completely revamped his appearance to prepare for his return as Duncan Idaho in “Dune Messiah.” This film is set to be the third and concluding installment of the acclaimed sci-fi series, which has secured eight Oscars.

“Only for you, Denis,” the actor said, referring to Denis Villeneuve, the director of “Dune: Part One” and “Dune: Part Two.”

The Hawaii native played Duncan Idaho in the 2021 film, but he did not appear in the 2024 sequel because his character died in the first film.

He revealed during a “Today” show interview in March 2025 that he is set to return in the third movie, thanks to his character being brought back as a clone.

The Hollywood star recorded a video of himself shaving off his well-known facial hair, which doubled as an advertisement for his eco-friendly bottled water company, Mananalu.

“It’s probably been six years or more since I worked on ‘Dune,’” Momoa mentioned. “What made that time remarkable was that it marked the launch of Mananalu. Back then, we were among the pioneers in introducing the aluminum bottle.”

The “Justice League” star highlighted his company’s collaboration with Boomerang Water, targeting the elimination of single-use plastics to benefit “our children and our planet.”

Momoa’s son, Nakoa-Wolf Momoa, will be part of the highly anticipated third installment of the “Dune” trilogy, according to Deadline.

Nakoa-Wolf was cast to play Leto II, the twin son of Timothée Chalamet and Zendaya’s characters Paul Atreides and Chani.

The A-lister’s son will star alongside “Silo” actress Ida Brooke, who will portray the other twin, Ghanima.

The “Minecraft Movie” actor shares two teenage kids, Nakoa-Wolf and daughter Lola Iolani, with his ex-wife, “The Cosby Show” actress Lisa Bonet.

The couple’s divorce was finalized in June 2024, seven years after they got married.

Momoa isn’t the only person getting a new look for the movie.

Eagle-eyed fans noticed that Chalamet closely shaved the nape of his neck before an outing with girlfriend Kylie Jenner in St. Tropez on July 7.

The “Call Me by Your Name” actor wore a green bandana over a navy Nike hat, so fans couldn’t get a full look at how much hair had been buzzed away.

“Dune Messiah” is scheduled to be released in December 2026.
