Diane Kruger and Joshua Jackson are splitting up after a decade together—also known as "an eternity" in Hollywood. Reps for both actors confirm to People that they "have decided to separate and remain friends." Jackson, 38, and Kruger, 40, who never married, were last seen walking the red carpet together in February. Then, in March, rumors of a breakup went around, but Kruger insisted to Elle that they were not true; in fact, at the time, the couple had just moved in together in New York. (Kruger previously split her time between Paris and Vancouver, Us reports.) They were spotted together publicly as recently as Saturday, the day after Kruger's birthday.
