The 37-year-old singer's songs will provide the soundtrack to 'Once Upon a One More Time', a tale that "explores an alternative arc for some classic fairy tale princesses", theatre owner James L. Nederlander has announced.
The 'Toxic' hitmaker is "so excited" about the project and has already attended some of the readthroughs of the script.
She said in a statement: "I'm so excited to have a musical with my songs -- especially one that takes place in such a magical world filled with characters that I grew up on, who I love and adore."
The show - which will feature 23 of Britney's songs, including her biggest hits and "a couple of deep album cuts" will begin previews in Chicago on October 29 ahead of opening on November 13 until December 1 at the James M. Nederlander Theater, and will then look to transfer to New York's prestigious Broadway theatre district.
