When Britney Spears clicks her fingers Simon Cowell comes running - or so it's rumoured as she gears up for the X Factor this weekend.
The pop princess is apparently back to her former bratty ways, demanding two Winnebagos and a private green room backstage.
The luxury motorhomes and chill-out area for Brit to change costumes even surpasses diva Mariah Careys requests for her appearance on the show two weeks ago.
A source tells The Sun, “Even Mariah got ready in the caravan, although Simon also gave her his green room. He’ll do the same for Britney.”
The singer will perform her single Womanizer on this Saturday's show - her first live appearance on UK soil in over two years.
No pressure then...
