Harry Hains, an actor and producer who had appeared on “American Horror Story: Hotel,” “The OA,” “Sneaky Pete” and “The Surface,” died on Tuesday. He was 27.

Hains’ mother, actress Jane Badler who starred on NBC’s sci-fi series “V,” confirmed her son’s death in a heartfelt Instagram post Thursday night. “On Jan 7 my beautiful son died,” she wrote. “He was 27 and had the world at his feet. But sadly he struggled with mental illness and addiction. A brilliant spark shone bright too short a time .. I will miss you Harry every day of my life …”

Born in Melbourne, Australia, Hains then lived in London and New York, but was residing in Los Angeles at the time of his death. Badler did not state the cause of death, saying only that a service will be held at the Hollywood Forever Cemetery in Los Angeles on Sunday on Jan. 12 at 3 p.m.

Along with his TV roles, Hains was also a model and a musician, performing under the stage name of Antiboy.

In March, Hains self-identified as gender fluid in an interview with Boys by Girls. “The ideas of gender, sexuality and race are social constructs,” Hains said. “I know that I am born male, but I don’t think I represent what it means to be a man. I believe we should be whatever we want. It gets kind of confusing when we start labeling ourselves so I try to stay away from labels.”
