RadarOnline.com is reporting that troubled actor Charlie Sheen will not be allowed to see his twin boys, Bob and Max, until he submits to a psychiatric examination.

The 45-year-old actor has not seen the twins since police officers made him surrender them to their mother, Brook Mueller.

Mueller got a restraining order against her soon-to-be ex-husband and the two are involved in an ongoing custody battle over the kids. Mueller has the primary custody of the boys.

RadarOnline.com is reporting that Mueller's and Sheen's custody agreement states that Sheen have a full psychological evaluation.

Charlie must submit to a mental health evaluation with a licensed professional before he can see Bob and Max, a source is quoted saying to RadarOnline.com.

Charlie won't see the boys until he sees a psychiatrist that is someone neutral, that hasn't previously treated him.

According to the report, Sheen has not undergone the tests yet.

RadarOnline.com had reported a while back that Mueller demanded that Sheen take a psychological exam because she was extremely concerned for the safety of the twins when around Sheen.

If he wants to see them, he will do it. Charlie agreed to these terms in the custody agreement. He has to adhere to the terms. The fact is though that before Charlie's problems began in the last several months, he had little or no contact with Bob and Max in the previous 16 months, the source told RadarOnline.com.
