Rockers INXS have sacked JD Fortune, the lead singer they recruited through a reality show, with the star admitting fame drove him to drugs.

The singer, who was picked to front the group after winning the series "Rockstar: INXS," said he was now broke and living in his car in native Canada after being dumped by the band at a Hong Kong airport.

"I was in an airport at Hong Kong and literally got a handshake. They said, 'Thank you very much'," Fortune told Canada's Entertainment Tonight.

"I found myself really alone because I had traveled with these guys for 23 months.

"I don't know where I am going, from sofa to sofa, from night to night. I am trying to get through my life."

Fortune - real name Jason Dean Bennison - said his departure could have had something to do with his cocaine use.

"It got as bad as it needed to be for me to numb out the fact that I knew this was going to come to a screeching halt," he said.
