After eight years of marriage, Josh Brolin and Diane Lane are splitting, their reps confirm to PEOPLE.
“They’ve been separated for several months. This was a hard decision for both of them to make,” says a source close to the couple. “The relationship just ran its course.”
The pair, who married in a 2004 ceremony at Brolin’s central California ranch, were first introduced by the actor’s stepmother, Barbra Streisand, at a party in 2002.
Brolin, 45, was recently arrested and held for public intoxication just before midnight on New Year’s Eve 2013, but he was released without charge.
