Brooke Mueller dogs charlie sheen sunglasses

Despite being in a vicious custody battle with ex husband Charlie Sheen, Brooke Mueller looked calm as she walked her dogs on Sunday in Los Angeles. The 36-year-old took her two pups on a dog walk and was accompanied by a friend.

Just last week, Brooke 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.

Last week, Brooke met with the Los Angeles Department of Children and Family Services after Denise Richards, who was caring for the boys at the time, wrote a letter detailing the boys' disturbing behavior and stating that she no longer wanted custody of them.

Muellers brother, Scott, was granted temporary guardianship of the twins, 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 Twitter last week, slamming his ex-wife for being "evil" and "pathetic."
