Jessie J 'an impossible diva'
Jessie J is reportedly "getting far too big for her boots."
The 24-year-old singer acts as a judge on the UK version of talent show The Voice.
BBC1 Controller Danny Cohen stopped by the set of the show recently and Jessie is said to have snubbed him while he stood outside her dressing room.
"Jessie is getting far too big for her boots. Nobody can believe what an impossible diva she has become," an eyewitness told British newspaper the Mirror.
"It was extraordinary, Danny is the most senior man at BBC1 and The Voice is his baby. He's the man who flew over to Holland personally to sign a huge deal and buy the show, and he's invested an enormous amount of his own time and energy in the format because he knows a lot rides on it."
"More importantly he was the man who gave Jessie J a job and turned her into a household name, so nobody could believe it when she left him standing outside in the corridor like a lemon."
Jessie recently appeared on the Graham Norton Show where she called parts of the singing competition show "lame."
