Does Andy really have ADD?

I heard on some website he has ADD and he takes a long time in his dressing room because he gets distracted. I was just wondering. Even if he does have ADD it doesn't make like him any less. I also प्यार psychology so I'm interested when someone या people believe a celebrity has a disability या a condition. Weird I know right....if anyone can answer my सवाल that would be appreciated. :)
