Demi Lovato to Bath Salt Rapping X Factor Hopefuls: See Ya!

Be warned, future X Factor hopefuls: Demi Lovato means business. Especially when it comes to drugs.

The new judge - whose history with substance abuse is well-known - reportedly stopped a couple of contestants in their rapping tracks this week because their lyrics included references to "bath salts," a synthetic powder that has been compared to cocaine and crystal meth - and was even rumored to be responsible for zombie attacks in Miami earlier this year.

Said an E! News source of the Greensboro audition:

"She wasn't having any of it. She said 'It's really irresponsible to be rapping about drugs in front of kids.' Then they tried to make excuses and Demi said, 'You talked about bath salts, I heard you.'"

Lovato ordered the young rappers to exit the stage, the insider added, and the "rest of the judges completely backed her."

Between this example, and reports that Britney Spears recently walked off the X Factor set because a drag queen tried to pay tribute to her with a rendition of "(You Drive Me) Crazy," there's little doubt:

Season 2 of the Fox competition will bring the serious drama!
