Jennifer Lopez and Ben Affleck's romantic afternoon interrupted by a flat tire

Jennifer Lopez And am AffleckTheir romantic afternoon had a wrench thrown in it… or rather a tire – because one of them broke down and ended their date

The lovebirds were driving around Los Angeles in a silver BMW on Saturday when they suffered a flat tire, bringing their couple's outing to an unfortunate halt.

Bennifer hopped out to check the damage — with Ben in a flannel and baseball cap, while J Lo rocked a tight black turtleneck and matching leggings.

Affleck and Lopez both got their hands dirty leaning over the car – while Ben's shirt lifted up to reveal his infamous back tattoo – but ultimately they couldn't solve the problem.

Ultimately, Lopez and Affleck simply had to leave the car. They asked for a ride to pick them up and left the Beamer behind as they headed for greener pastures.

It's unclear who picked up the BMW or whether it was taken to a shop, but this is far from the first time Ben has had car trouble… and his luck seems more than a little worse than that of the average motorist on the road.

Remember last year when Ben's was classic Cadillac broke down during a heat wave in the City of Angels? Or when his son Samuel accidentally backed a rental Lamborghini in another car?

Yep, it sure seems like bad luck plagues the movie star everywhere he drives.

It seems like the rest of the day went great for the couple… it did at the Lakers game last night – apparently it's going to take more than a flat tire than to keep the couple off the court seats.
