Brooke Mueller has cooperated with authorities and agreed to have her four-year-old twins Bob and Max tested for fetal alcohol and drug syndrome, according to Radar.

Brooke met with the Los Angeles Department of Children and Family Services last week after Denise Richards wrote a letter detailing the boys' disturbing behavior and stating that she no longer felt capable of caring for them. Mueller’s brother, Scott, was granted temporary guardianship of the twins on Friday, and a source close to the situation tells the website, “The good news is that they will now be properly tested, and monitored. It will be crucial that DCFS follows up and follows through with whatever the testing reveals. The boys' lives literally depend on it.”

Multiple sources confirmed to Radar that "Brooke did indeed also drink large amounts of alcohol while pregnant ... This was on top of the drug use which included meth." Not only that but she also went to rehab twice during her pregnancy ... Yikes!

Charlie Sheen has been very vocal about Brooke being an unfit parent, as he posted numerous messages on Twitter last week, slamming his ex-wife for being "evil" and "pathetic." (For the record, he also called her a "wh*re" and posted a photo of a cake with a grenade on it and addressed it to her.)

And now a production company is trying to put together a reality show on the Anger Management star's family drama and get this -- they also contacted Dr. Charles Sophy, the Medical Director of the L.A. County Dept. of Children and Family Services, who lives in the same gated community as Sheen, Richards and Mueller! TMZ reports that the company "wants to do a loosely-based series and asked Dr. Sophy if he was interested in helping," and Sophy "in no uncertain terms said he was not interested."

We can't imagine Denise would go for that, but if it makes Brooke look bad, we're guessing Chuckles will be on board!
