Singer Kelly Osbourne is said to be acting like a diva backstage at "Australia's Got Talent".
The 31-year-old's behaviour has left staff "walking around on eggshells" so they don't set her off, according to New Idea magazine.
The magazine claims that the show's co-judge keeps a sign on her door so no one disturbs her in between takes, reports mirror.co.uk.
And when the camera is rolling, the magazine alleges that she is constantly asking for touch-ups from the make-up team.
According to reports, she's banned people from chewing gum in her presence because "the sound annoys her".
Her representative declined to comment on the reports.
