Let's hope her stage performance is more exciting than this outfit!
Looking a little tired from celebrating on Christmas (and one of her few days off), Katie still managed to show off a half smile for the paps before heading inside the theater.

Oh well, we bet she must have really warmed up once she hit the stage!
