IMHO, she's an excellent choice - her sense of humor (and yes, she does have one) is very dry, her timing is impeccable, and whether or not she is a "STAR" in the bankable sense, she is every inch a STAR personality on stage, and that's what matters for the role. Again: IMHO.
Cheyenne Jackson tickled me. AFTER ordering SoMMS a drink but NOT tickling him, and hanging out with Girly in his dressing room (where he DIDN'T tickle her) but BEFORE we got married. To others. And then he tweeted Boobs. He also tweeted he's good friends with some chick on "The Voice" who just happens to be good friends with Tink's ex. And I'm still married. Oh, and this just in: "Pettiness, spite, malice ....Such ugly emotions... So sad." - After Eight, talking about MEEEEEEEE!!! I'm so honored! :-)
