“Diane Kruger and Josh Jackson have decided to separate and remain friends,” reps for both confirm exclusively to PEOPLE.
Kruger, 40 and Jackson, 38, began dating after Kruger split from her husband of five years, French director Guillaume Canet.
Kruger and Jackson owned houses in both Paris and Vancouver, and lived together in New York, where they were often spotted taking strolls around the city.
The two last stepped out together in February for the opening of Jackson’s Broadway play.
