Demi Lovato has a fun new job that’s “cool for the summer.”

The singer, who is currently on her Future Now tour with Nick Jonas, took a break from performing in Denver, Colorado to go undercover as a Lyft driver named Samantha.

“I actually really want to be a singer someday,” Lovato, 24, tells one unsuspecting passenger in a video, shared exclusively with PEOPLE, from her stint as a Lyft driver.

“Like, I’ve actually been traveling the country with my ex-boyfriend’s brother because he sings, too,” continues Lovato. “And so we really want to kind of get our names out there at open mic nights and, like, whatever we can do.”

And the star – who sang a few songs (including a Camp Rock tune and “Happy Birthday”) with her passengers – even made a few jokes about herself throughout the video.

“I like that ‘Confident’ song,” says one of the singer’s passengers. “That’s a jam.”

“I like that one, but like, sounds like she’s screaming,” replies Lovato. “Selena [Gomez] is so much more talented.”

“She’s got such a better voice,” adds Lovato.
