Actor Harry Hains, best known for his appearances in FX’s “American Horror Story” and Netflix’s “The OA,” died on Tuesday, his mother, actor Jane Badler, announced Friday on Instagram. He was 27.

“On Jan. 7 my beautiful son died. He was 27 and had the world at his feet. But sadly he struggled with mental illness and addiction,” Badler captioned a photo gallery. “A brilliant spark shone bright too short a time … I will miss you Harry every day of my life.”

A memorial service will be held in Hains’ honor at Los Angeles’ Hollywood Forever Cemetery on Sunday.

Hains appeared in one episode of “American Horror Story,” in addition to Amazon’s crime drama “Sneaky Pete” and Netflix’s sci-fi drama “The OA.” He also had roles in indies, including the 2015 drama “The Surface.”
Born in Melbourne, Australia, Hains was living in Los Angeles at the time of his death.

Badler, also an actor, starred as Diana in NBC’s 1980s sci-fi drama “V” and its 2009 remake. She also played Shannon Reed in the “Mission: Impossible” TV series.
