The quote and pic are from Details June/July 2006 issue (page 86):
"It's all a vast conspiracy, of course. And Kelly Clarkson is the mastermind. 'Fans on her boards like to hate on Clay; They're nervous about Clay outshining Kelly,' explains Donna Anderson, a fan from Phoenix. She Pauses. 'I know, I know, it sounds very paranoid...'" Yeah Donna, it kinda does. She is quite certainly talking about the John Paulus thing.
Oh, and there's an actual Clay Aiken mangina pic after the jump.
