Ten-time Grammy Award-winning artist Pharrell Williams is set to turn his smash hit song "Happy" into a children's novel to be released next fall with a first-printing of 250,000 copies of the book.

According to the Washington Post, the book will be published by Putnam, a division of Penguin-Random House, and will be filled with pics of kids from all around the globe "celebrating what it means to be happy."

"I'm humbled by the global success of 'Happy,' but especially in awe of the song's young fans. My collaboration with Penguin allows me to continue a dialogue with these children in a fresh, new way. We're both committed to feeding the curiosity of young minds with imagination," the 41-year-old Williams said in a statement.

In all, the deal Williams inked with Putnam calls for the creation of four new picture books, according to Billboard.com.

The youth market doesn't come as a new one to the fedora-wearing Williams. His music was featured in the children's movies "Despicable Me 2" and "The SpongeBob Movie: Sponge Out of Water."

Williams penned his first book in 2012, entitled "Places and Spaces I've Been." The tome focused on his work and "contribution to contemporary culture" and featured excerpts from rap stars Jay-Z and Kanye West, Vogue editor Anna Wintour and astronaut Buzz Aldrin.

Besides writing the two-time Grammy winning "Happy," the prolific Williams has also worked with artists like Nelly, Gwen Stefani and Kellis to create such hits as "Hot in Herre," "Hollaback Girl" and "Milkshake."

Williams foray into the world of transforming his songs into children's book follows a pattern started by Bob Dylan in 2011 when he adapted his hit "Blowin' In The Wind" into a kid's book. A year later, Bob Marley's eldest daughter converted several of her father's hit songs into book, among them "One Love" and "Every Little Thing."
