Demi Lovato went undercover as a Lyft driver. The singer surprised unsuspecting fans by pretending to be a driver during a tour stop in Denver, Colorado. Wearing a hat and oversized shades, she posed as an aspiring singer named Samantha.

"I actually really want to be a singer someday. Like, I've actually been traveling the country with my ex-boyfriend's brother because he sings, too," Demi said, referring to her tourmate and Joe Jonas' brother Nick Jonas. She also sang and got nostalgic about her Disney days.

The "Cool for the Summer" hitmaker also roasted herself and took a jab at fellow Disney alum Selena Gomez in the process. "I like that one ['Confident' song] but it sounds like she's screaming," She said. Despite clearly having more powerful pipes, she added, "Selena's so much more talented. She has such a better voice."
