Simon Cowell's nickname for his new The X Factor judge, Demi Lovato, is "the brat" and he might have good reason for it after all.

While judging a performance, Simon suddenly turned to Demi to ask her opinion and the pop singer obviously wasn't expecting it. Her mouth was visibly full of mints!

So what's a girl to do? As you can see in our exclusive video, she took one of Simon's hands and spit them into it.

"Really, really grown up, Demi," Cowell growled. "You're an obnoxious little brat."

Hopefully she won't do the same on September 11, when The X Factor becomes the first TV show to ever host a red carpet premiere at the legendary Grauman's Chinese Theatre in Hollywood.
