After eight months of negotiations, pop superstar Britney Spears has signed a $15-million deal to join Simon Cowell's "The X Factor" as a judge, reports E! Online.
The insider continued, "She can't wait to sit down next to Simon at the judges' table and give this everything she's got… This is the perfect next stage in her career. Both Britney and Simon are very excited to work together."
Executive producer Cowell fired judges Paula Abdul and Nicole Scherzinger, and host Steve Jones at the end of the show’s first season -- and has been searching for replacements since.
Songwriter L.A Reid has already been signed as a judge alongside Spears and Cowell. Possible candidates for the fourth and final judge include former Disney stars Miley Cyrus and Demi Lovato.
