Britney Spears wants Demi Lovato to join her on US 'X Factor'.

The pop princess will reportedly receive $15 million to join Simon Cowell and L.A. Reid on the judging panel of the pop star search show and has asked that Demi be considered for the final position because she believes they would have great chemistry together.

A source told RadarOnline: "Britney is the anchor of the new judging panel and that was Simon's most important hire. Britney is extremely hopeful that Demi Lovato will become one of the judges because she truly admires her. Britney loves how open and honest Demi has been with her fans after she went to rehab last year. She thinks they have a lot in common and that they would have great chemistry on the show. Britney is being kept apprised of the status of ongoing contract talks with Lovato and it is looking like she will be joining the show! Britney is extremely excited for filming to begin, which will be in the next month.

"Britney and Demi have met a few times very casually at Hollywood industry parties but those were very brief. Demi went to one of Britney's concerts in Anaheim in 2011 and met with her backstage. Once Demi officially signs her contract Simon will have the new judging panel over to his house for a celebration dinner. The second season of 'X Factor' is going to be amazing."

Judges Nicole Scherzinger and Paula Abdul were sacked after one season on the show.
