The 19-year-old former star of Disney Channel's "Sonny with a Chance" is to join pop star Britney Spears, Simon Cowell and LA Reid as judges on Season 2 of the singing competition show next fall, the report said.
Paula Abdul and Nicole Scherzinger were fired as judges after the first season of "X Factor" aired and wasn't a ratings winner. Their replacements -- Lovato and Spears -- are expected to be officially announced this week.
"X Factor" is based on a British series by the same name.
