The memoir shines a light on Obama's childhood, life with former President Barack Obama, their time in the White House and more. It was an immediate success, selling 2 million copies in just 15 days, according to the book’s publisher.

The former first lady was previously nominated in the best spoken word Grammy category in 2012 for the audio version of her first book, "American Grown."

Barack Obama has sealed two wins in the same category for his books, "The Audacity Of Hope: Thoughts On Reclaiming The American Dream" and "Dreams From My Father."
