Lil’ Chris, who was found dead last week, had mental health issues and depression, his relatives said.
The 24-year-old singer, whose real name was Chris Hardman, was found in Lowestoft, Suffolk, on March 23.
A statement from his family said: “Chris had struggled with mental health issues and depression in recent years.
“He was committed to helping others find better ways of overcoming this illness and publicly said he wished to find a cure.”
Fellow musicians and fans paid tribute on social media to Lil’ Chris, who rose to fame in Channel 4’s Rock School in 2006.
The statement said Lil’ Chris was a “huge personality who will be missed by everyone who knew him”.
“He was a hugely creative person who used this side of his personality to make others smile, to cheer people up and to make others feel better.
“A real people person, he would always take the time to stop and talk, no matter who or when and we are proud that he was so well thought of by all who knew him.
“So many commented on what a lovely, well brought up person he was, so polite and kind and a pleasure to know.”
The singer’s family said his funeral would be invitation-only and those attending would be asked to wear green, which was Lil’ Chris’ favorite color.
