Many celebrities like to branch out into other ventures once they succeed in their primary career field. Many actors, singers, and athletes have done everything from starting companies to writing books. Many have authored children's books, including Reese Witherspoon, Dolly Parton, and Seth Meyers to name just a few.

This list is by no means conclusive. There are plenty of other celebrities not on this list who have written children's books that have sold well. But for the sake of time and space, let us focus on these ten. One might wonder how well a children's book by Kelly Clarkson or Gabrielle Union sells. Spoiler alert: most of the books on this list made it to the New York Times bestsellers list.

10 I'm Not Scared, You're Scared by Seth Meyers

I'm Not Scared, You're Scared teaches children that being afraid is not a bad thing, but that it is when you let your fear control you that you have a problem. The book is an adage to the old lesson that courage is not the absence of fear, but the overcoming of fear. The book was illustrated by the artist Ray Sayegh, Jr.

9 River Rose and the Magical Lullaby by Kelly Clarkson

The American Idol star and popular TV host joined the publishing world with this story about a girl who goes on a journey thanks to a magical lullaby that is sung to her by her mother.

7 Sulwe by Lupita Nyong'o

This bestseller by the Mexican-Kenyan actress is about a girl who wants to be beautiful, and she thinks that can only happen if her dark skin is made lighter. The book highlights the very real issue of colorism, a byproduct of racism and white supremacy. The book was highlighted on Netflix's series Bookmarks: Celebrating Black Voices.

6 The One and Only Sparkella by Channing Tatum

On the outside, Tatum has the face of an action hero and the body of a male stripper (he literally used to strip before he became an actor). But on his more family-friendly side, he wrote The One and Only Sparkella, which Google Books calls, "a charming ode to self-esteem." The book quickly hit number one on the NYT list when it came out in May 2021.

5 Coat of Many Colors by Dolly Parton

Named after her famous song, this book tells the story of a girl who needs a new warm winter coat. The book also uses lyrics from Parton's song. This is not Dolly Parton's only book, she also co-wrote a suspense novel called Run Rose Run with the notorious best-selling author James Patterson.

4 Your Baby's First Word Will Be Dada by Jimmy Fallon

Fallon's book uses pictures of cute animals to help parents and children alike come to terms with the way kids grow up. A child's first words are a pivotal turning point, and often a child's first words are either "Mama" or "Dada" as M sounds and D sounds are two of the easiest sounds for those developing language skills to make. Fallon wrote a sequel, You're Baby's First Word Will Be Mama, to make sure moms get equal representation.

3 The World Needs More Purple People by Kristen Bell

This book plays on the old phrase "I don't care if someone is black, white, or purple, but..." The phrase is often said before a tone-deaf or racist comment, but Bell uses that as a jumping-off point to create the idea that a purple person is fun, accepting, loving, and a joy to be around. The book is recommended by SocialJusticeBooks.org and it quickly became number 1 on the bestseller list.

2 Busy Betty By Reese Witherspoon

This book is the newest on this list at the time it was written, it came out in October 2022. Witherspoon has already written other books, most of them for children. Busy Betty is a story about a girl who faces a big challenge when she is tasked with bathing her dog.

1 The Adventures Of Qai Qai by Serena Williams

Serena Williams might have retired from Tennis in 2022, but now she has plenty of time for her hobbies, like her pottery and her writing. In this story, a little girl learns to believe in herself thanks to the help of her doll Qai Qai, which comes to life to take the little girl on all sorts of adventures. The book was praised in Oprah Daily, a feat that many authors seek to achieve besides the NYT list.
