Mueller agrees to have her sons' checked

Socialite Brooke Mueller has agreed to have her twins Bob and Max tested for "fetal alcohol and drug syndrome".

The 36-year-old will reportedly have her children with Charlie Sheen tested to see whether they have mental and physical defects, which can develop in a fetus due to high levels of alcohol consumption during pregnancy, reports radaronline.com.

It is believed the Los Angeles Department of Children and Family Services (DCFS) thought it was a necessary move and Mueller wants to cooperate.

"Brooke did indeed also drink large amounts of alcohol while pregnant. This was on top of the drug use which included meth," a source said.

"Child services demanded Brooke sign off on having the boys tested and assessed for fetal drug and alcohol syndrome," another source said.

This comes after Sheen's other ex-wife, actress Denise Richards, who was granted temporary custody of Bob and Max in May until the end of this year, wrote to the DCFS to inform them she can no longer care of them as they are violent towards her own children and dogs.
