Demi Lovato slams Simon after he says she's "very annoying".
Demi Lovato and
Simon Cowell appeared on
Conan on Monday and, as expected, their appearance was not dull. Not at all.
The
X Factor judges didn't shy away from revealing what they think about each other. From
Demi criticizing
Simon's too-tight T-shirts, to him calling her "annoying" and to her telling him that he can be "a bit of an asshole", it was all very entertaining.
Check out the video of
Lovato calling
Cowell an "asshole" after he says she is "very annoying":
