She had a real hot streak during this period - Legally Blonde TV show, Legally Blonde tour understudy who was surrogate lead for large stretches, lead on the Grease tour, Glinda understudy, all in 3 years and all before she was 22 at most.
I still cringe when I remember asking if she was Amanda Jane Cooper or Lauren before the show I knew it was one or the other. then after the show I couldn't find my Legally Blonde thing for her to sign lol found it in the car on the way home
