Extra host Mario Lopez is writing a childrens’ book. The notorious womanizer, who successfully authored Mario Lopez’s Knockout Fitness earlier this year, has teamed up with his sister, Marissa, to pen Mud Taco, an illustration work of fiction based on Mario’s own experiences as a growing up in California.

“Mario wants to share his amazing experiences as a kid,” an insider tells In Touch Weekly. “It’s called Mud Taco, and it’s based on Mario’s experiences growing up.”

The insider adds: “For fun, he and Marissa would make tacos out of mud in the backyard, substituing worms for cheese, grass for lettuce, and mud for meat..Now they’re writing a book about it to teach children to be strong and creative.”

Mud Taco will be published by Penguin Books next year.mario-lopez1
