Child Protective Services has been formally notified that Adrienne Maloof and Paul Nassif's son, Christian, had three broken fingers when his Real Housewives of Beverly Hills star mother brought him to the emergency room at Cedars-Sinai Medical Center, Breaking Celebrity News is exclusively reporting.

"Anytime a child comes to the hospital and suffers a mysterious or hard to explain injury, Child Protective Services is immediately notified. In this case, because Christian suffered three broken fingers under mysterious circumstances, the attending physician in the emergency room reported the injury to Los Angeles County of Department of Children and Family Services. This is always done out of an abundance of caution, and is done for the safety and well being of the child, always. It is concerning that this is the second time that social workers have been notified about an incident involving Christian Nassif in the past two months," a source close to the situation tells Breaking Celebrity News exclusively.

As previously reported, Adrienne Maloof rushed one of her three sons, six-year-old Christian to the emergency roo at Cedars after he suffered the injury.

During the contentious divorce between Maloof and plastic surgeon Nassif, he was investigated by social workers from Los Angeles County of Department of Children & Family Services concerning allegations that he allegedly abused their three boys.

According to a sworn declaration from the couple's marriage counselor, Dr. Charles Sophy: "On Sunday, September 16, 2012, Adrienne called and told me about an incident involving Paul and the children that occurred on Thursday, September 13, 2012. Specifically, Adrienne told me that Paul and the children were in the car when Paul became angry in response to Collin kicking Christian's seat, and that he tried to hit the kids while they were all in the car."
