Charlie Sheen’s ex-wife, Brooke Mueller has asserted that she will only allow the “Two and a Half Men” actor to see their twins if his so-called ‘goddesses” will undergo drug test.

With the help of the authorities, Mueller had taken her the twins, Bob and Max, from Charlie’s home, which the actor has fondly called “Sober Valley Lodge”.

She was granted by the court of the custody allowing her to take the kids from Charlie when she argued in a sworn statement that Sheen had threatened her and said: "Cut your head off, put it in a box and send it to your mom."

An unidentified source explained to RadarOnline.com that Mueller refused to be around Sheen’s girlfriends, judging by the nature of their jobs: a porn star and a marijuana magazine cover model.

The source said, "Brooke doesn't want the girlfriends around her sons. One is a porn star, and the other is a marijuana magazine cover model. Brooke is seeking to control who is around the boys when Charlie has custodial time with them."

Cited by RadarOnline, the source clarified however that Brooke vows to adhere what the court has ordered her to do as far as her children are concerned.

"Brooke will abide and respect whatever the court orders her to do. She has been sober for approximately one week, and the boys are being cared for by Brooke and her mom at an undisclosed secure location right now," the insider has revealed to RadarOnline.

Mueller’s apprehension has remained a hurdle for Sheen to see his twins. Though Charlie had passed the recent tests he had undergone over the past weeks, his ex-wife has remained largely concerned of any drugs she suspects to be somewhere in Sheen’s “Sober Valley Lodge”.

"Brooke believes that just because Charlie is clean, for now, doesn't mean that his house is drug free. She is very, very concerned about the people that are in Charlie's life,” the source said, according to RadarOnline.

Mueller’s challenge to have Sheen’s goddesses drug tested came after his two live-in girlfriends, model/nanny Natalie Kenly and Rachel Oberlin also known by XXX fans as porn star Bree Olson, have released images of Brooke’s hotel room with drug paraphernalias all over it.

Brooke’s camp has maintained that she has been undergoing rehabilitation herself and has improved immensely since she began the program. The court now has granted temporary custody of their children.
