Diane Lane has already pulled the trigger in her divorce from Josh Brolin, filing the papers in L.A. Superior Court and citing irreconcilable differences.
Lane signed her divorce documents on Valentine's Day, citing February 13 as the date of their official separation, although sources say it was earlier than that.
"They've been separated for several months. This was a hard decision for both of them to make," says a source close to Diane Lane and Josh Brolin.
"The relationship just ran its course."
The pair, who married in a 2004 ceremony at Brolin's California ranch, were introduced by his 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.
He was also arrested for fighting in a bar in Louisiana in 2008, where drinking was involved. Charges were eventually dismissed in that case, too.
Four months after they married in 2004, Brolin was arrested for spousal battery, but Diane Lane recanted her story and charges were never filed.
In any case, the divorce documents cite "irreconcilable differences." Lane also wants her name restored to Diane Lane (it's legally Diane Lane Brolin).
