She will be in the show for six weeks, December 1-January 10.

Whitney Leavitt, known for The Secret Lives of Mormon Wives and Dancing With The Stars, will star as Sandra Dee in the musical Just in Time at Circle in the Square Theatre. Leavitt joins the cast for a six-week engagement December 1-January 10.
When Leavitt made her Broadway debut as Roxie Hart in Chicago earlier this year, she spoke to TheaterMania, saying, “I grew up dancing, I graduated [with a degree] in fine arts, and I’ve always had a passion for performing… The reality show organically happened and I just kind of went for it. But this was always the goal for me.”
Developed and directed by Tony Award winner Alex Timbers, Just in Time currently stars Jeremy Jordan, Olivia Holt, Carrie St. Louis, Tony Award winner Debbie Gravitte, Joe Barbara, Drama Desk Award nominee Emily Bergl, Lance Roberts, Caesar Samayoa, Christine Cornish, Julia Grondin, Valeria Yamin, Jaime Foord, Tari Kelly, Matt Magnusson, Jeffrey Schecter, and Tristen Buettel.
