Demi Lovato is irritating: Simon Cowell
London: Music mogul Simon Cowell has branded Demi Lovato as "obnoxious and irritating" in a speech he gave at the opening of the Teen Choice Awards.
Cowell, 52, who works with Lovato on the US version of `The X Factor`, said he loved her really but also found her to be "very annoying", reported Femalefirst.
"She`s annoying, obnoxious, disruptive, gobby, irritating, bad manners, not great taste - did I say irritating? Yes? Annoying, very annoying. She`s a brat.
"I could go on for hours, but that`s what makes her special, and I really do love her, a bit. Have a great night, wish I was there, but no one invited me," he said.
