Britney Spears’ return as a judge on next season’s The X Factor was blocked by the show’s producers after she wanted too much money, Breaking Celebrity News is exclusively reporting.

The I Wanna Go singer demanded $18 million -- a $3 million pay rise on her previous contract -- to appear on the talent competition in 2013.

But those connected with the FOX series felt that the 31-year-old Toxic singer just wasn’t worth the hefty price tag!

“When producers asked if she wanted to return for a third season of The X Factor, Britney's reps said she would only come back if she was offered $18 million,” a source tells Breaking Celebrity News.

“But after much deliberation, they just felt that Britney wasn’t worth that much because she wasn’t bringing enough to the table.

“Her performance as a judge was scrutinized, and she didn’t really add anything to the show. They felt she didn’t warrant a $3 million pay hike.
