Kelly Clarkson wrote a children's book about her daughter

Kelly Clarkson had been teasing a project with her daughter, River Rose, for a while.

There were clues:

Clue No. 1

Clue No. 2

Clue No. 3

Clue No. 4

Balloons, magic and a lullaby? What could it all mean...

Ah, yes, a children's book.

In a video, Clarkson said she started writing "little stories," because River Rose was going on trips to "all of these amazing places that she was too little to remember. Those snippets were turned into the book River Rose and the Magical Lullaby. (Watch through 'til the end of the video to see River Rose having "attitude.")

The singer/songwriter/author said she hopes children can "be inspired by it and know that can achieve anything."

And if the literature doesn't work, there's always her song Stronger. (And for parents, her newer Piece by Piece.)

The book comes out in October.
