Simon Cowell is used to prima donna behavior but a British publication claims his new “X Factor” judge Britney Spears is taking it to “another level.”

The pop star is allegedly making some outrageous demands on the set of the Fox singing competition, with a long list of eye-rolling requirements.

Among the dressing room items necessary to keep Britney happy: 10 bags of Doritos, 12 Snickers bars, six cases of Diet Coke, 10 pieces of chicken and 12 vases of magnolia blossoms.

She also needs her own beauty team, including a personal manicurist, facialist and massage therapist. Oh, and throw in 34 Herve Leger dresses too.

Britney also must have a personal spiritual advisor by her side backstage, as well as a doctor, a psychologist and a security team.

Simon may be laughing off Brit Brit’s diva demands for now, but the report also claims the reality TV guru won’t be out the entire $15 million bucks he’s reportedly paying Spears should she not work out, since she’s being paid per episode.

Season 2 of “The X Factor” premieres in September featuring Britney Spears and Demi Lovato at the judges’ table alongside L.A. Reid and Simon Cowell.
