Demi Lovato got right the the point on the premiere of X-Factor. The singer, 19, relayed a message from Niall Horan to fellow judge, Simon Cowell. Niall, 18, knows Simon from when he and the rest of One Direction appeared on the British version of the show. Demi and Niall have been spotted together recently, so Demi's comment fuels the rumors that she might be dating theBritish heartthrob. It's clear from Simon's comments that he disapproves of the relationship!
