Anger Management star Charlie Sheen is 'absolutely disgusted' the Los Angeles County Department of Children & Family Services is allowing ex-wife Brooke Mueller's sober coach to conduct her drug tests as she tries to regain custody of their twin sons, Bob and Max, Breaking Celebrity News is exclusively reporting.

"Charlie suspected that Brooke's drug tests weren't being conducted by an independent person/agency because his lawyer had been asking for the results of those tests, and was shot down every time. On Thursday morning after Breaking Celebrity News published the shocking news that Brooke's drug tests were being done by her long time sober coach, and paid employee, Carmine Thompson, Charlie was absolutely disgusted," a source close to Sheen told Breaking Celebrity News.

"He doesn't understand why DCFS and the judge would allow this. It doesn't make any sense at all. If Brooke didn't have money, she would be required to submit a test to a laboratory appointed by officials. She is calling all the shots! Remember, this is someone that has been to rehab over 20 times, and twice while pregnant!"

Thompson, a respected board registered interventionist, is employed by Mueller, 36, and has been on/off for the last five years.
