Charlie was out Thursday in Bev Hills when a photog asked him about Brooke's latest battle with addiction, and as it turns out -- he'd just gotten off a phone call about that very subject. Charlie said someone had told him about his ex-wife reportedly checking into a trauma center to seek professional help for substance abuse.
The news comes after a years-old video started circulating reportedly showing a woman identified as Brooke doing crystal meth. She reportedly also tried to score drugs last month in the Hamptons.
Charlie -- who has 10-year-old twin boys with Brooke -- said the kids are doing great. The boys, Bob and Max, are reportedly staying with Brooke's parents while she's in rehab.
