Nyong'o has acquired film rights to the award-winning novel, Americanah.
Back in March, author Chimamanda Ngozi Adichie hinted that she was working on something with Lupita Nyong'o but wouldn't go into detail.
The secret is finally out and Adichie announced Thursday that Lupita Nyong'o has optioned the film rights to her novel Americanah.
According to The Root, the news was revealed by Adichie and announced via Stylist Magazine's Twitter account saying, "Lupita Nyong'o has optioned rights for the film version of Americanah, Chimamanda Ngozi Adichie confirms #stylistbookclub."
The novel is a love story that follows a young couple from Nigeria who face hard choices and challenges in the countries they come to call home. Americanah was selected as one of the 10 Best Books of 2013 by the editors of the New York Times Book Review, also winning the 2013 National Book Critics Circle Award for Fiction.
Adichie is not stranger to the big screen, her book Half of a Yellow Sun is playing in theaters now and stars Chiwetel Ejiofor and Thandie Newton.
This will be Nyong'o's first major film announcement since her Academy Award winning performance in 12 Years a Slave.
