Love can make the world go round, but it can’t keep your car from breaking down.

Justin Bieber and girlfriend Hailey Baldwin learned this the hard way on Monday when their car broke down while on vacation in the Hamptons.

The “Sorry” singer’s Mercedes-Benz SLS — a nearly $230,000 luxury sports car, complete with gull-wing doors — decided to stop working in the middle of an intersection.

Unable to move the obstruction themselves, police were soon called out to their location to help direct traffic and make the situation safe until a mechanic could come out to tow the expensive ride.
