Demi Lovato plays games with Britney Spears on `X Factor`

London: 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," quoted the 20-year-old as saying.
