Billy Ray Cyrus and Kelsea Ballerini are lending their voices to two new episodes of a Nickelodeon cartoon. The country artists will each appear in upcoming episodes of Blaze and the Monster Machines.

In Blaze and the Monster Machines' animal-themed "Wild Wheels" episodes, Cyrus and Ballerini will voice animal-esque trucks. Cyrus character, which will appear in the episode "Animal Island," is Lazard, a selfish lizard truck who wants to steal magical powers all for himself; Ballerini's character, meanwhile, is Tooks, a toucan truck who tries to play a game with some new friends but encounters trouble along the way.

Blaze and the Monster Machines follows the adventures of a monster truck named Blaze and his 8-year-old diver, AJ. The pair's adventures are meant to help teach pre-school-aged children about the STEM (science, technology, engineering and math) subjects.

The Blaze and the Monster Machines episode in which Cyrus appears, "Animal Island," is scheduled to air on May 29 at 12PM ET. Ballerini's episode, "Toucan Do It!," is scheduled for 12PM ET on May 31. More information about Blaze and the Monster Machines can be found on the show's website.

Musically, Cyrus is celebrating the 25th anniversary of his smash-hit single “Achy Breaky Heart.” Ballerini is at work on her sophomore album.
