Diane Lane, Josh Brolin call it quits

(CNN) -- Diane Lane and Josh Brolin are splitting up after eight years of marriage, reps for Brolin tell CNN.

The reps didn't provide any other details other than to confirm that "Diane Lane and Josh Brolin have decided to end their marriage."

The actor pair tied the knot in August 2004, and it was the second marriage for both. "Gangster Squad" star Brolin, 45, has two children from his previous marriage to actress Deborah (Alice) Adair: Trevor, 25, and Eden, 19.

"Man of Steel's" Lane, 48, has a daughter, 19-year-old Eleanor, from her prior marriage to actor Christopher Lambert.

According to Us Weekly, the couple have been broken up for a couple of months. An inside source tells the magazine that their breakup was a mutual decision.

"It is very amicable," the source said. "It's not ugly, it's just over."
