Demi Lovato Disses Simon Cowell on “Conan”

Posted Tuesday September 18, 2012 2:30 PM GMT

Playful banter has always been the name of the game on “The X Factor,” and last night Demi Lovato and Simon Cowell brought their bickering to “ "Conan."

During their interview, the talent show co-judges hyped up the new season and even took a few jabs at each other.

Conan brought up a past quote from Cowell in which he referred to the “Skyscraper” songstress as “annoying.”

Simon reasserted his opinion, which led Demi to share some sentiments of her own- “You can be a bit of an a**hole,” she quipped with a chuckle.
