Beyonce talks about Chimamanda Adichie's influence on her music in Mini Documentary:' 'Imperfection''

Bey featured author of Americanah, Chimamanda Ngozi Adichie on a track titled “***Flawless” in her 5th solo album that took the music world by storm and crashed iTunes!
In the second part of her mini-documentary explaining the album, Beyoncé says she could identify with Chimamanda's views on feminism when she found her  TED talk speech on YouTube titled, “We Should All Be Feminists”. Bey says, “Everything she says is exactly how I feel.”

Incidentally, Chimamanda Ngozi Adichie’s “Americanah” not only made the cut as one of  The New York Times’ 10 Best Books of 2013 but also came top on the list of BBC's 10 Best Books of 2013.

The New York Times review on Adichie's Americanah;

By turns tender and trenchant, Adichie’s third novel takes on the comedy and tragedy of American race relations from the perspective of a young Nigerian immigrant. From the office politics of a hair-braiding salon to the burden of memory, there’s nothing too humble or daunting for this fearless writer, who is so attuned to the various worlds and shifting selves we inhabit — in life and online, in love, as agents and victims of history and the heroes of our own stories.

Other books on the list include Life After Life by Kate Atkinson, The Sleepwalkers by Christopher Clark and Days of Fire by Peter Baker.

While BBC gave this exceptionally good review:

Chimamanda Adichie is supremely smart. She has won the Commonwealth Writers' Prize (for Purple Hibiscus), the Orange Broadband award (for Half of a Yellow Sun), and a MacArthur 'genius' grant. With Americanah, a star-crossed love story that spans three continents, she proves she is also supremely funny.
Ifemelu leaves her boyfriend behind in Nigeria to study in the US. After her initial disorienting days as an immigrant and a string of humiliating jobs, she finds an outlet in a satiric blog. "Dear Non-American Black, when you make the choice to come to America, you become black," she writes. She becomes a Princeton fellow and dates a Yale professor. After 13 years her heart brings her back to Lagos, where she is not 'black'. She's Igbo. And Americanah.
Adichie is fearless when writing about love, hate and shades of blackness. She tempers her directness with wry humour as she holds up a mirror so we can see ourselves. (Knopf)
