Adrienne Tells All! Maloof Gives DCFS Interview Amid Child Abuse Claims

Adrienne Maloof has formally been interviewed by child protective services as part of an ongoing investigation targeting her ex-husband, Dr. Paul Nassif, RadarOnline.com has learned.

The allegations involve the couple's three children, Gavin, 12, and twin sons, Colin and Christian, 6.

The former Real Housewives of Beverly Hills star, 54, "has been interviewed by the Los Angeles Department of Children and Family Services," a source told RadarOnline.com. "Social workers asked how the kids were doing, and other routine questions that are commonly asked. Adrienne's primary concern is the kids and their well-being. Period."

The abuse scandal began when Nassif's former bodyguard, Kevin Villalobos, stated in his resignation letter, "I could not silently standby while you hit and injured your children in angry outbursts." The letter was also sent to Maloof. Nassif later sued Villalobos for defamation over the claims, but that wasn't enough to stop the investigation.

Villalobos made a formal complaint with officials, and as RadarOnline.com reported, a DCFS investigation against Nassif was launched. Insiders said the case is likely to be dismissed, and a source insisted, "Paul is a dedicated dad, and is fully cooperating with the investigation. He has nothing to hide."
