"My biggest regret in life is that I never met Madeline Kahn and Leonard Bernstein, that's the two people I would have loved to have met. I'm hoping she's proud of me." Kristin Chenoweth hopes her idol approves of her performance in the new Broadway revival of the late actress' hit musical On The Twentieth Century. Kahn, who died from cancer in 1999, originated the role of Lily Garland when the play debuted on the Great White Way in 1978.
