London, Sep 17 :  Singer Demi Lovato and Britney Spears passed the time during breaks on the set of "The X Factor" playing games.

The pair joined the panel of judges this year and Lovato revealed they quickly bonded over "tic tac toe and doodle".

"We bonded at 'The X Factor's boot camp. During breaks we'd sit behind the panel and use the paper to play tic tac toe and doodle," contactmusic.com quoted the 20-year-old as saying.
