Jason Momoa's girlfriend reacts as fans are left speechless after he shaves off beard for the first time in six years

Jason Momoa's girlfriend has reacted to his shocking new look after shaving off his beard.

The Game of Thrones alum shared an Instagram video of him shaving off his iconic beard and it's left his fans floored.

Why has he shaved off his beard, I hear you ask? As a way of promoting his new bottled water brand Mananalu.

In a bid to reduce the use of single-use plastic, the bottled water comes in a reusable aluminum bottle.

He's also reportedly needing to be clean-shaven for his upcoming role in Dune 3.

"Haven’t shaved in six years, and here we are again," Momoa captioned the video. "I launched @mananalu to help eliminate single-use plastic. Now, we’re taking it even further, partnering with our team at @Getboomerangwater to bring in a closed-loop system that sanitizes and bottles water onsite."

Momoa went on: "That means even less waste, reduced shipping footprint, and our aluminum bottles get reused over and over. This is the future, and we’re starting in Hawai’i.

"Let’s get rid of single-use plastic. For our children and for our planet. All my aloha, j."

In the video Momoa admitted himself that he 'hated' his new look, but his 16.8 million Instagram followers have been much kinder about his baby-face appearance.

"He is beautiful no matter what. Thanks for using your platform for good @prideofgypsies," somebody commented.

Another echoed: "You look great and the work you're doing is so very important."

A third penned: "You look great either way!!!!"

Others said that having no beard made the 45-year-old actor look younger.

Momoa's girlfriend has also commented on the post. He's dating Hit Man and Andor star Adria Arjona.

The couple went public with their relationship in May 2024 on social media and have since been seen at a handful of red carpet events together.

Like many of his fans, Arjona has shared her support for her beau's unexpected new appearance and replied to his viral post with a string of heart emojis.

Before dating Arjona, Momoa had been with Lisa Bonet for 16 years, four of which they were married.

Bonet filed for divorce from the Dune actor in 2024.

They announced their shock separation in 2022 in a joint statement that read: "We have all felt the squeeze and changes of these transformational times…A revolution is unfolding and our family is of no exception…feeling and growing from the seismic shifts occurring.

"And so we share our Family news that we are parting ways in marriage."

It continued: W"e share this not because we think it’s newsworthy, but so that as we go about our lives we may do so with dignity and honesty. The love between us carries on, evolving in ways it wishes to be known and lived.

"We free each other to be who we are learning to become… Our devotion unwavering to this sacred life & our Children. Teaching our Children what’s possible. Living the Prayer. May Love Prevail."

Bonet and Momoa are parents to Lola, 18, and Wolf, 16.
