Yes she does, but I would be careful, because I told her that I loved her performance etc. etc. and she hugged me for so long that her personal security detail had to pull her off of me, so be warned if you don't like touching people.

I saw a Wednesday matinee show and she did not come out to sign or take pictures. They handed out pre-signed programs with Alan Cumming and Michelle's autograph to anyone at the stage door. My friends and I stayed around anyways and Michelle came out and said a quick hi before riding off on her bike.
