Demi Lovato not afraid of Simon Cowell

Singer Demi Lovato says she is not afraid of making her "The X Factor" co-judge Simon Cowell angry with her witty comments.

Asked on the show if she is worried about making Cowell, 53, angry, Lovato, 21, said: "I don't really know for sure and I don't really care if he does because I'm going to do it anyway and that's what he gets for hiring a -- at the time a 19-year-old -- to be alongside him on the judges table."

This is for the second time Lovato is judging the competition. She joined the "The X Factor" in the last season of the show.

Singers Kelly Rowland and Paulina Rubio are also seen as judges on the show, which airs on BIG CBS LOVE.
