London: Pop superstar Michael Jackson once hid in a secret underground tunnel at a concert to avoid talking to his staff, according to his voice coach.
~Yvie Burnett, who tutored Leona Lewis when she won Britain's The X Factor in 2006, worked with the Thriller hit maker during a tour and was stunned by his rude behaviour, OK! magazine online reported.
"I remember a long time ago, I was working with Michael Jackson and he had a tunnel built which took him from the stage into the dressing room. He crawled into this big white tunnel so that he didn't have to speak to any of us," Burnett said.
"He was probably the rudest (celebrity) because we all went up to meet him and he wouldn't speak to anyone, not even the crew who were beside him," she added.
