Sam Smith's Carpool Karaoke Welcomes Special Guests - Watch Now!

Sam Smith got a big surprise during his Carpool Karaoke – a visit from Fifth Harmony!

The video first showed Sam and James jamming out together to some of his hits including “By Your Side” and “Money on my Mind.”

Later on in the car ride, Sam admitted he’s a “harmonizer.” Sam and James started singing their hit “Work From Home,” when suddenly James got on his cell phone saying something was missing. Suddenly, Fifth Harmony approached the car and jumped in!

“Oh I’m dead,” Sam said.
