RockersВ INXS have sacked JD Fortune, the lead singer they recruited through a US 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 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 travelled 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.
