My bet is that Kelley has generated enough popularity that she could survive one bad performance. But she better step it up next week.
When the show started and I saw all 12 there she realy stands out. She didn't look to be the least bit worried about getting kicked off.
That is exactly what kellie has done. Much like Bosurvived the horrible disaster of his Broadway night performance. She has consistently been on of the top 3 women every week, and that coupled with her humorous schtick has garnered her one hell of a fan base.
