Her biggest role to date may be that of reporter Charolotte Dennon in the 2012 production of the Christmas musical Elf.
She's had several theater roles, both on Broadway and on national tours, in plays and musicals such Monty Python's Spamalot, Bells Are Ringing, and Oh! What a Lovely War, as well as the role of Linda Low in a 2003 touring production of Flower Drum Song. (She's also done a couple of movies, including Woody Allen's Blue Jasmine.)
She even played a snake charmer in the 1997 Broadway musical Side Show, which, alas, not too many people were in a hurry to step right on into. Too bad . . . they missed one gorgeous snake charmer. :-)
