Olivia Rodrigo worries she's a 'bad influence' on Jimmy Kimmel's kids as they sing her songs

For a "homeschooled girl," Olivia Rodrigo sure knows how to go to school in style.

On Tuesday's episode of "Jimmy Kimmel Live!" the hitchhiking Grammy-winning singer joined the Kimmel family during their morning commute to school in Los Angeles' San Fernando Valley. After Kimmel and Molly McNearney's kids, 9-year-old Jane and 6-year-old Billy, recovered from their shock, they banded together to sing some songs off Rodrigo's latest album, "Guts," from the backseat.

With Rodrigo sitting in the middle, she, Jane and Billy belted out their favorite songs, "Ballad of a Homeschooled Girl" and "Get Him Back!"

"He wants to get him back for you," Molly explained about Billy's favorite track off "Guts." "And then what do you want to do when you get him back?" she asked her son.

"Punch him in the penis," he responded seriously of his plan to help the singer out. The song is about Rodrigo wanting to win a guy back, despite knowing they have a history that's very "up and down."

"Oh, my goodness!" Rodrigo exclaimed as Jane covered her face. "Am I a bad influence on your children?" she asked McNearney and Kimmel.

"He's always been this way, don't worry," Jane replied.

Olivia Rodrigo apologizes for Jimmy Kimmel's son singing her explicit lyrics

Though more than half of the tracks on "Guts" − including "Get Him Back!" − are explicit, this was Rodrigo showing restraint. Back in Kimmel's studio, she told the late-night host that she did "pare it back" when it came to profanities on her sophomore album.

"We have to make sure to listen to the clean versions of your songs because the 'Vampire' song has a catchy little lyric in there that our son started singing back to us," Kimmel told her.

"Oh, my God, I'm so sorry. I'm such a bad influence," Rodrigo said.

She also confirmed the four-letter word trend for her album titles, revealing a joke her producer made while they were recording "Guts."

If you listen close enough to what "sounds like ambient noise" at the end of "Teenage Dream," her producer says, "What should the next four-letter album title be, 'Fart?' "
