After initially posting a series of broken heart emojis on her Instagram Story, the 22-year-old then shared an image of Cloud under which she wrote, "My heart is so broken. I love you forever."
She also shared a 2022 video—set to Kendrick Lamar's "Money Trees"—in which the Euphoria actor can be seen smoking while Martin smiles in the background. As she wrote over the video, "A song he loved."
In another slide, Martin—who guest starred on the season two premiere of the HBO hit—shared a collage of the two, which included pictures of them cuddling, holding hands and a graffiti Christmas tree that her on-again, off-again love seemed to paint for her. "I will never let the world forget you," she wrote, "bless bless 1 love."
The 25-year-old's family announced his passing on July 31, just a week after they laid Cloud's father to rest in Ireland.
"He buried his father and intensely struggled with this loss," a statement from the family read. "The only comfort we have is knowing Angus is now reunited with his dad, who was his best friend. Angus was open about his battle with mental health and we hope that his passing can be a reminder to others that they are not alone and should not fight this on their own in silence."
They added, "We hope the world remembers him for his humor, laughter and love for everyone. We ask for privacy at this time as we are still processing this devastating loss."
While a cause of death has not yet been revealed, his mom Linda Cloud McLaughlin placed a 911 call regarding a "possible overdose," multiple outlets report.
Shortly after news of his death was shared, HBO released a honoring Cloud, who played Fezco on Euphoria.
"We are incredibly saddened to learn of the passing of Angus Cloud," the network said. "He was immensely talented and a beloved part of the HBO and Euphoria family. We extend our deepest condolences to his friends and family during this difficult time."
