After looking at her pics, like this one..I do think it's her. It's the same bone structure, and she's just looking very casual at the show. It also clinched it-like you said Lindsfan, that she is so cool during landslide. Just not a fangirl vibe during Stevie songs, which would be expected. I'll have to look for Lynn and Mick's kids, since I didn't catch that one! Wish this uploader had the bug incident "Without You" video
It was just cool to see that angle!
