The star, who played Arnold Jackson in the hit series from 1978 to 1986, coining the catchphrase “What you talking ’bout, Willis?”, was taken to hospital on Wednesday (May 26) after a fall at his home in the US state of Utah, and passed away later that evening.
Blink-182 bassist Mark Hoppus paid tribute to the late TV actor, posting on his Twitter page: “I hope that in heaven Gary Coleman finds the peace that eluded him on Earth, and finally discovers what Willis was talking about.”
Katy Perry also lined up to offer her respects, while Janet Jackson tweeted: “I’m at a loss for words upon learning of Gary Coleman‘s passing. I want to remember him as the fun, playful, adorable and affectionate man he was. He has left a lasting legacy. I know he is finally at peace.”
The former child star never grew taller than 4ft 8in (1.4m) because of a kidney condition. He also had two failed kidney transplants.
