Simon Cowell is Richie's favorite judge

Nicole Richie is a big fan of American Idol's Simon Cowell, despite his insulting the shape of her mouth to her father Lionel. "My favorite judge is Simon Cowell because he's honest and funny. Although Simon and I had a bit of an issue, I don't remember why...maybe he said something to my dad, like he didn't like my mouth. But we finally met at an industry event and made up," Nicole said recently.
