"I thought The Apple Tree was hard. This is really really hard!" Chenoweth said of the musical. "I'm enjoying it because I'm challenged. It's operetta, but it's comedy. It's lots of dancing."

The role of Lily Garland was performed in the original 1978 production of the musical by Madeline Kahn. Chenoweth, who has long expressed her admiration for the comedic actress, named her dog after her.

"My biggest regret in life is I never met Madeline Kahn... I'm hoping she's proud of me," Chenoweth said.

Chenoweth also discussed her two upcoming films, the thriller "The Boy Next Door," in which she co-stars with Jennifer Lopez, and the animated film "Strange Magic."

Chenoweth won the Tony Award in 1999 for her performance in You're A Good Man, Charlie Brown. She was nominated in 2004 for her performance in Wicked and has also been seen on Broadway in Steel Pier, Epic Proportions, The Apple Tree and Promises, Promises. The actress is also known for her award-winning film and television work, including "Glee," "Pushing Daisies" and the recent ABC series "GCB."
