Big news!

Kelly Clarkson finally revealed that big project she was teasing -- a children's book starring her adorable 1-year-old daughter, River Rose!

"My hope is for little kids to read River Rose and the Magic Lullaby, and be inspired by it," Clarkson says of the book, which comes out Oct. 4. "And know they can achieve anything. Dream big and make big thinks happen."
