Watch: Kristin Chenoweth Celebrates Her Birthday With a Mouthful of Cake Onstage at The Queen of Versailles

Happy birthday, Kristin Chenoweth! The Tony-winning Broadway star celebrated her big day July 24 in the best way possible for a theatrical diva: onstage after taking her bow, starring in the world premiere musical The Queen of Versailles. Currently playing a Broadway-aimed run at Boston's Colonial Theatre, the show reunites Chenoweth with her Wicked songwriter, Stephen Schwartz.

And Schwartz was on hand to help mark his star's birthday. In a video she posted to Instagram, a visibly moved Chenoweth accepts a beautiful bouquet of flowers from the composer-lyricist before giving the audience a look at her days on the pageant circuit as they all sing her "Happy Birthday." See her follow that up by taking a big chomp out of her birthday cake in the video below.
