The two-act evenings, directed by Richard Jay-Alexander of "Les Miserables" fame, mark Chenoweth's first solo concert at the Hollywood Bowl.
Chenoweth, Jay-Alexander and Mary-Mitchell Campbell devised the show, which will feature music from Hollywood in the first act and "pure Chenoweth" in the second.
"This has been a dream of mine, not unlike, earlier this year, when I got to play the Sydney Opera House in Australia," the Broadway star said.
"I gave this particular show a lot of thought and even had special clothes designed for this two-night engagement. Every time I'm in a fitting, for the opening dress, I look at myself in the mirror and get excited and nervous, like a bride. I just want it all to be magical... out in the open air, and for everyone to have a beautiful evening. I'll be jealous that everyone out there will be having lovely food and drinks and I’ll be onstage, working!"
The 45-year-old actress will be joined by Constantine Germanacos, Jennifer Diamond and Johnny Stellard with special appearances by "Avenue Q" characters Lucy T. Slut and The Bad Idea Bears.
"Working with Kristin has been a dream come true for me," Jay-Alexander said. "It's endless discovery and awe, in both gleaning material and witnessing her gifts and growth from rehearsal to rehearsal. She takes her work very seriously... and that, for me, is a real pleasure."
Chenoweth is best known for her performance as Sally Brown in "You're a Good Man, Charlie Brown" on Broadway, for which she won a Tony Award, and for originating the role of Glinda the Good Witch in the musical "Wicked."
