This is all happening so fast we can barely keep up!
Allison shared the exciting news on her brand spankin' new Instagram account and said she was thrilled to be taking on the iconic role! But she didn't stop there, as she also shared a pic of herself in costume!
That's right! We have our very first pic of Allison dressed as Peter Pan on the same day as the announcement!! How exciting!!
Ch-ch-check out the first pics of Allison in costume (below)!
OK, so we have a teeny tiny confession to make…
That's NOT Allison in costume for the upcoming live musical. However, it IS Allison proving that she's actually been prepared to play this role since she was a little girl!
Also, we gotta admit she makes a pretty adorable Peter Pan!
