Chris Brown is without a publicist just weeks away from his Australian tour.
Brown's publicist has quit after he stormed out of a TV studio earlier this week.
The 21-year-old singer will no longer be represented by Tammy Brook ' whose clients include former boxer Mike Tyson ' as she has reportedly ended their working relationship days after he trashed his dressing room in outrage after being questioned on 'Good Morning America' about his 2009 assault on then-girlfriend Rihanna.
Despite his outburst, Chris ' who later accused the show of 'exploiting' him as he wasn't expected to be quizzed over the attack ' is reportedly set to be invited back on the programme.
An insider told E! Online: "It's all about the ratings. At all other costs."
Following the incident on Tuesday (22.03.11), Chris - who is alleged to have been screaming so loudly that worried hair and make-up personnel called security before he ripped off his shirt and left the building - apologised for his actions and admitted he was 'disappointed' in himself.
He said: "I want to apologise to anybody who was startled in the office, anybody who was offended or really looked disappointed at my actions because I was really disappointed in my actions.'
