Joanna Gaines has revealed her latest project--a children's book. According to The Hollywood Reporter, the Fixer Upper star shared the news on social media Monday. Gaines wrote, "Today's the day! We get to finally share this project the kids and I have been working on. We wrote this children's book together to tell the story of our journey in the garden--a story of trying and failing and trying again and never giving up." Her older children Duke, Drake, Emmie Kay and Ella Rose are co-authors of We Are the Gardeners. (Six-month-old son Crew was probably too young to contribute.) The book will be released on March 26.
