After initially asking "X Factor" bosses to "Gimme More," Britney Spears has reportedly reached an agreement to serve as a judge on the TV talent show.

Spears, 30, will join Simon Cowell's show at a price of $15 million, according to The Wrap. About $13 million will come for her judging role and the rest will be paid for her to perform on the US show.

She will serve on the program's judging panel alongside Cowell and producer LA Reid.

Earlier reports claimed Spears had been offered a $10 million deal to judge the show, but had demanded $20 million.

FOX and Spears' representatives have so far made no comment about the reported agreement.

The payday would compare to the salary paid to Spears' former "Mickey Mouse Club" pal Christina Aguilera, who earns about $10 million on "The Voice."

Judges Paula Abdul and Nicole Scherzinger departed "X Factor" after its first season, along with host Steve Jones.

FOX Broadcasting is owned by News Corp., the parent company of NewsCore.
