The Indian actress will star in the musical titled "Miss Bollywood" to open in London in September and later travel to Broadway.
"The whole song-and-dance routine of a musical really fascinates me and I think I'm a natural in the art," The Sun quoted her, as saying.
She said the musical was about a day in the life of a Bollywood actress and would give Westerners a preview of Indian traditions and customs.
The 32-year-old actress shot to international fame after British contestant Jade Goody bad-mouthed her in the Celebrity Big Brother racism scandal earlier this year.
