Britney Spears takes a portable dentist chair everywhere
The 30-year-old singer has the reclining furniture flown by private jet to the `X Factor` auditions so she can relax in comfort while her fellow judges Simon Cowell, Demi Lovato and L.A. Reid are forced to sit in fold-out directors` chairs.
A source told The Sun newspaper: "She`s got a portable dental chair and she loves it. It reclines so she can relax while they make her up.
"We joke with her about it all the time. It`s a running joke amongst her whole team.
"We make sure it`s in every city she goes for the auditions - and it always travels by private jet."
Despite her attention-grabbing chair, Simon insists Britney is very "shy".
He told People: "She`s not on the show to be BritneySpears on a TV show.
"She`s actually there to prove to the world there`s more to her, and she`s got the ability to do this job really well. She`s taken the role really seriously.
"It`s quite interesting because when someone has done what she`s done as she has with her career, and being such a public person, you kind of think she is going to be very confident, but in real life she`s shy. There`s kind of a mystique about her which I think is what kind of attracted me to her in the place."
