Demi Lovato has officially joined US X Factor, it has been reported.
The 19-year-old actress and singer has signed a deal to take a seat on the panel of Simon Cowell's programme and is heading to New York for the formal announcement, reports TMZ.com.
Demi - who sought treatment in 2010 as she was battling bulimia and bipolar disorder - will join Britney Spears, Simon and music executive LA Reid on the judging panel when the programme returns in September.
Simon and LA were already judges, but newcomers Demi and Britney will be filling the spots vacated when Nicole Scherzinger and Paula Abdul were axed following the show's first season.Demi and Britney have both been in the frame for a while, and Britney is thought to have finalised her deal last week. It has been reported that she will pocket 15 million dollars for season two of the show.
