Jessie J may be dumped from The Voice because of her attitude, according to reports.

The 24-year-old singer recently appeared on the Graham Norton Show where she called parts of the singing competition show "lame."

Britain's Daily Mirror newspaper claims that the show's producers are looking to Cheryl Cole, Adele and Kylie Minogue for guest slots in an effort to shake up the programme that has lost four million viewers in the past two weeks.

"Many of the show's most senior staff are angry that Jessie criticised the show's production values so publicly," an insider told the publication. "She is paid a huge amount of money to be a big part of the show, and should be one of the show's most vocal supporters."

Although most of Jessie's comments did not air on the late night talk show they were widely reported.

BBC bosses are also said to be annoyed with Jessie's tardiness and her large entourage.

"With Jessie in particular, the staff are becoming frustrated that she is so unapproachable," the insider added.

"She turns up with a legion of minders, assistants and hangers on and is sometimes late too. It's like an audience with the Queen although Her Majesty's timekeeping is probably better."
