Josh Brolin and Diane Lane
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.
Spotted without his wedding ring the following day, Brolin, donning sunglasses, seemed unfazed by the trouble as he ate with a male friend at Sauce on Hampton in Venice, Calif.
A few days later, Lane, 48, headed to the Palm Springs Film Festival – without her husband – where she presented an award to her former Unfaithful
costar, Richard Gere.
Brolin was previously married to Alice Adair, with whom he had two children. Lane previously wed Christopher Lambert, and they had one child together.
