According to People, the Gangster Squad star recently checked into a rehab facility in Northern California.
The actor—who is in the process of divorcing his wife, actress Diane Lane—made headlines recently after he allegedly got drunk and fought a bar patron at O’Brien’s Irish Pub in Santa Monica, Calif.
The incident was caught on tape, and two days later, Brolin told TMZ that he was planning to get sober. Asked if he regretted his behavior from Nov. 2, he replied, “Absolutely. It won’t be happening again.”
