Jason Momoa took to Instagram on Thursday to honor the memory of his late grandmother, Mabel, on the one-year anniversary of her passing.

Sharing a collection of photos featuring moments with Mabel, the Aquaman actor reminisced about their cherished memories together. “I LOVED MAKING MY GRANDMA LAUGH. It’s been a year now, I miss u grams. I wish she got to see this last movie; she would have been so happy,” wrote Momoa, 43, in his heartfelt caption.

The series of images included screenshots of FaceTime calls between Momoa and his grandmother, a snapshot of Mabel seated inside a Ford Thunderbird, and a tender moment captured with Momoa embracing Mabel.

Reflecting on their bond, Momoa shared, “I would FaceTime her when I was playing FLIP in slumberland, and she was so giddy seeing me dressed up like a wild animal. I got the news when I was giving a speech to the UN on Aquaman, talking about saving our beautiful planet. I think the scene didn’t make the cut, but it was a hard day, and she was right there with me.”

Expressing regret for not being able to be physically present with his grandmother, Momoa added, “It’s tough when u can’t make it home to see your loved ones. I’m sorry for that, grams. Today will be hard, but I have the best angels watching over me. ️️️️️ Mabel lemke.”

Momoa had previously shared affectionate moments with his grandmother on social media, including a surprise visit home to Iowa in January 2019. During that visit, he posted pictures of himself and Mabel, capturing their bond and his love for her.

In one photo, they smiled together for the camera, while in another, they sat side by side, gazing out of the window. Momoa humorously noted the geographical reversal between Hawaii and Iowa, adding a playful touch to his tribute to his home states.

Additionally, Momoa shared a glimpse of his entire family gathering outside an Iowa diner during his visit, expressing pride and love for his relatives. He later uploaded a video to YouTube titled “Visited my home state of Iowa!” showcasing moments from his trip, including heartfelt reunions with family and cherished time spent with his beloved grandmother.

Momoa’s touching tributes to his grandmother highlight the enduring love and connection he shared with her, as well as the profound impact she had on his life.
