Another alumna of a Fox music competition show is heading to Glee. Following the news that Adam Lambert would appear on the show's upcoming season, X Factor judge Demi Lovato is also joining the cast for a "significant arc," according to TVLine.com .
According to TV Line , Demi, who's been focusing on her music rather than her acting in the last few years, will play Dani, a struggling artist friend of Rachel and Santana's. She'll interact with Adam Lambert's character -- who's been described as "Kurt's nemesis" -- and they'll perform together as well.
Demi will appear in at least six episodes, beginning with the one airing October 3. She shooting will be scheduled around her X Factor duties, TV Line reports. This is the singer's first major acting role since her Disney show Sonny with a Chance went off the air two years ago.
American Idol season 11 runner-up Jessica Sanchez has also appeared on Glee.
