Lil Nas X is connecting with his younger fans!

The 21-year-old "Old Town Road" rapper released his children's book, C is for Country, on Tuesday.

"I’m dropping the best kids' book of all time soon!" the star wrote when announcing the book on Twitter in September, adding to his followers that he "can't wait to share it with you all."

On Tuesday, the singer took to Twitter again to encourage his fans to buy it.

"My children's book C is for Country is out now!" he wrote. "Go get it please. I really need to pay my rent!"

The children's book, which is being published under Random House Kids, a division of Penguin Random House, is currently available for order online.

Illustrated by Theodore Taylor III, the children's book includes "plenty of hidden surprises for Nas' biggest fans," the website says.
