#4. Kristin Chenoweth
Claim to Fame: Chenoweth has starred in a number of films (Bewtiched, The Pink Panther) and a number of TV shows (The West Wing, Pushing Daisies) but her heart was always in the theater. Her Broadway highlights include roles as Glinda in Wicked and Sally Brown in You're a Good Man, Charlie Brown. She's also noted for her distinct singing voice which actually sounds a lot like Betty Boop. We'd love to help her hit the high notes.
