Michelle Obama‘s ‘Becoming’ continues to make history. The highest selling book of 2018 is now officially the longest-selling No. 1 book on Amazon, surpassing a two-month run on top.

According to CNN, Obama’s book knocked out Fifth Shades of Grey, the first book in what became a film-spawning series. Becoming tells stories of Obama’s upbringing in Chicago to her life in the White House and having all eyes on her. In a recent interview with Oprah Winfrey, Obama shared that she wasn’t hesitant to show the world certain aspects of her life.

“…because here’s the thing that I realized: People always ask me, ‘Why is it that you’re so authentic?’ ‘How is it that people connect to you?’ And I think it starts because I like me. I like my story and all the bumps and bruises,” Obama said. “I think that’s what makes me uniquely me. So I’ve always been open with my staff, with young people, with my friends. And the other thing, Oprah: I know that whether we like it or not, Barack and I are role models.”

Obama is currently in the midst of an intimate conversation tour and she’ll be in Houston in March.
