Paula has some health issues which explain her sometimes erratic behavior. She is such a nice person and I hate to see people misunderstanding her.
Here is a link about it, and I'm sure there is a lot elsewhere on the web: http://www.usatoday.com/news/health/...dul-pain_x.htm

I actually fell asleep watching Idol this week. Probably had more to do with me than the show...but anyway, I'm still a KATHARINE fan!! The quality of her voice is amazing. I loved her hair this week - so stunning!
