I did go watch from the windows into the gym...just for a minute... and she was slapping her rear end as she danced. LOVELY!!!!
I have to add though, that I was thrilled to death to see all the girls who came up to her individually and said hello, giving her one of those tween girl squeely hugs. What thrilled me was that they went up to HER to say hello. She gave a hug back, and said a nice hello, but I could see her eyes on the pizza line!
