It’s “Carpool Karaoke” meets “Taxicab Confessions.”

Pop star Demi Lovato took a break from her Future Now tour to pose undercover as Lyft driver and prank fans in Denver, Colo. Hidden cameras recorded their conversations; at one point Lovato even sang a duet with one of her passengers. The video was posted on Lyft’s YouTube channel as part of their Undercover Lyft series.

Lovato’s disguise was not very elaborate, consisting of just a hat and aviator sunglasses, but passengers were none the wiser. The singer — in her alter ego “Samantha” — even dropped some very obvious hints.

“It’s like a job that’s like, cool for the summer,” Lovato said, dropping the title of her 2015 hit.

Later she revealed, “I’ve actually been traveling the country with my ex-boyfriend’s brother,” in reference to her current tour with Nick Jonas (the younger brother of her ex Joe Jonas).

Lovato even poked fun at herself. When one passenger revealed she was going to see Eric Church instead of the Future Now tour, Lovato said, “that’s a better concert.” Later, Lovato brought up her friendly rival Selena Gomez. “Selena’s so much more talented,” she joked.

Gomez made headlines earlier this week when she announced she was taking a break to focus on her health. Gomez revealed she she suffers from the autoimmune disease lupus.
