"I have to tell you, I have a lot of street cred with my niece 'cause this is one of her favorite shows!" the singer, 30, said of Nickelodeon's hit animated preschool series about a little girl and her magical genie pals to People.
Pickler will play Zora, a genie pirate, in a two-episode story airing on Nick USA early next year. She will sing two original songs for the show.
The last time Pickler got animated - in 2014's Veggie Tales movie, "Beauty and the Beet" - she played a sweet potato ("the sweetest potato of them all," the singer pointed out). But this time around, her character - whom she says is "a tough chick and a free spirit" - hits a little closer to home.
"Zora and I are both adrenaline adventure junkies," says Pickler, who recently went skydiving with the Army's Golden Knights for an upcoming episode of her CMT reality series I Love Kellie Pickler.
"We're both always seeking the next crazy adventure," she adds. "Zora's a little spitfire. But she can be a little forgetful, a little absentminded at times - and we have that in common too."
Pickler says while she and her songwriter husband Kyle Jacobs have "no plans" for kids themselves, she's proud to be part of a show that children like her niece can enjoy.
"You have to be so careful not to contaminate their little minds," she says. "Once they hear something or see something, they can't un-hear it or un-see it!"
