Despite Jada Pinkett Smith revealing intimate details about her marriage to Will Smith, including being separated for the past seven years, her new memoir, Worthy, is failing to sell as many copies as expected. 

The book was released on October 17 and sits at number 81 on Amazon Books' bestseller list, according to Newsweek. The publication also pointed out that Worthy didn't make the top 100 of the Barnes & Noble and Publishers Weekly lists. 

Other celebrity books that have out-sold Jada's book include Arnold Schwarzenegger's self-help book, Be Useful: Seven Tools for Life, Britney Spears' The Woman In Me, and John Stamos' memoir, If You Would Have Told Me
