Oh please. Performing on the Grammy's was always a dream of hers. There's a video of her being all cute about it on Idol - and I think the Grammy's played it before she performed in 2006. Listen to THIS reaction - mid interview - when she found out she was nominated for her very first Grammy for Miss Independent way back in 2003.
And she was just as excited with the last few. And she cried on stage twice when she won her two Grammy's in 2006. She cares about the Grammy's a lot. I'd love to see you at 4:30 in the morning
