In the new book, Andrews, 79, will share stories of what happened behind the scenes of her biggest films, including Mary Poppins, The Sound of Music,Thoroughly Modern Millie, Victor/Victoria and more.
"My first memoir, Home, was about my childhood, early training and formative years in the Theater," she said in a statement. "I am so pleased that my good friends at the Hachette Book Group have encouraged me to share the next phase of my life, beginning with my arrival in Hollywood and the wonderful movies and television programs I was asked to be a part of."
In 2008's Home: A Memoir of My Early Years, Andrews revealed a story that she hadn't even told her siblings. As recounted in a New York Times review, "One evening when she was 14 and driving her inebriated mother back from a party, Barbara told her that her father was not, in fact, Ted Wells, but the man whose party they had just attended, with whom Julie remembered 'feeling an electricity...that I couldn't explain.'"
The new memoir will come out in September of 2017. Andrews' announcement comes just a few weeks after The Sound of Music turned 50 on March 2. Check out the video below to see her reveal secrets about The Sound of Music in the video below.
