RadarOnline is reporting that Gary Coleman has passed away. He was 42.

Coleman was hospitalized in Utah earlier this week for a head injury following a fall. He slipped into a coma while in the hospital and now his family has reportedly taken him off life support.

The Illinois native was perhaps best known for his role as Arnold Jackson in the sitcom Diff’rent Strokes. Coleman played a child who was adopted by a wealthy widower and he quickly became the star of the show with his catchphrase, “What’choo talkin’ ’bout, Willis.” Coleman stayed with the show until it went off the air in 1986.

After the show, Coleman made guest appearances on many different TV shows, including 227, Married with Children, Martin, and The Fresh Prince of Bel-Air. Although he enjoyed success as a popular public figure, Gary soon suffered from financial troubles and was forced to declare bankruptcy in 1999 due to mismanagement of his trust by his parents and former manager.

Gary earned some negative publicity when he allegedly assaulted a woman while working as a security guard. He later raised eyebrows when he appeared on Divorce Court with his wife, Shannon Price, due to marital problems although they eventually reconciled and remained together until his death.

Gary’s famously small stature was due to congenital kidney disease, which he contracted at a young age. Due to the disease he had two kidney transplants and required daily dialysis.

He will be missed.
