Following weeks of speculation, it appears that Demi Lovato will be factoring into Simon Cowell’s plans to revamp his hit reality singing competition series…

The 19-year-old part Mexican American singer/actress has officially signed on as the fourth and final judge for the upcoming season of Fox’s The X Factor, according to E! Online.

When X Factor returns in September, the former Disney Channel star will join newly appointed judge Britney Spears, who reportedly signed her deal last week, and last season’s judges Cowell and L.A. Reid.

Earlier this year, X Factor producers cleaned house by dismissing the show’s host Steve Jones and judges Nicole Scherzinger and Paula Abdul. In March, Reid and Cowell confirmed the two open judges spots would be filled by women.

It appears the “Give Your Heart a Break” singer and Spears beat out some stiff competition for the coveted judging spots, including Janet Jackson, LeAnn Rimes and Miley Cyrus.

As reported last week, Spears is said to be receiving $15 million for the season.

No word yet on the details of Lovato’s contract, but she is expected to appear at Fox’s upfront presentation on Monday with Spears, where the formal announcement will be made.
