Demi Lovato just doesn't want to listen to X Factor con­test­ants rapping about drugs.

Well, according to E!Online she doesn't. The 'Remember December' song­stress appar­ently rejected a duo from the stage at recent X Factor auditions for this very reason.

"She wasn't having any of it," claims a usefully unnamed source to E! News, "She said 'It's really irre­spons­ible to be rapping about drugs in front of kids.'"

Good point well raised Demi.

"Then they tried to make excuses and Demi said, 'You talked about bath salts, I heard you,'" the 'source' then continued.

The whole affair concluded with Demi telling the duo to get right out.

Bravo.
