Gabourey Sidibe to write autobiography

London: "Precious" actress Gabourey Sidibe has signed a publishing deal to write her autobiography, which she promises will be filled with 'impolite and shady' stories.

The 32-year-old actress has signed a deal with publisher Houghton Mifflin Harcourt (HMH) to pen her memoir, which is as yet untitled but will be released in 2017, reported Contactmusic.

"I've been writing since I was a child, and have always had so many stories to tell that are too long, shady, and impolite to share in interviews.

"It brings me much joy to add published writer to my resume of actor and part-time foot model," she said.
