Looks like "The Real Housewives of Beverly Hills" cast is just as dramatic off-camera as they are on-camera. 

Dr. Paul Nassif will not be divorcing Adrienne Maloof without putting up a good fight.

Maloof was granted a temporary restraining order from her estranged husband Nassif and received temporary custody of their three children on Sept. 19. 

Nassif has been accussed of choking and spanking one of his sons as well as kicking the family dog. 

He is being investigated by the L.A. Department of Children & Family Services over physical abuse allegations regarding his children, according to court documents RadarOnline obtained.

On Sept. 21, Nassif posted the following statement on his official Facebook fan page: "It continues to amaze me how so much of the hoopla surrounding a reality show is in reality, unreal -- including the absurdity of the latest utterly false accusations by Adrienne's attorney which we will vigorously address in court. It is becoming a bit of a circus isn't it? The phrase 'all is fair in love and war' must have been penned by a divorce attorney. I'm very disappointed in the ridiculous tactics that are being used that potentially compromise my relationship with my children. As I've said throughout this ordeal, the most important thing is the health, happiness and stability of my kids. I hate to see others using them as pawns. I'm going to stay utterly focused on their well-being and the knowledge they need equal time with both of their parents both of whom love them very much. I'm sure all will be fine and when all the emotion of the moment dies down, Adrienne and I will be terrific co-parents."

A source close to Nassif told People magazine that he plans to "go back to court and fight" the temporary restraining order against him.

"He will put forth witnesses that will be absolutely as credible as anyone she's putting forward. It looks like both sides are digging in for a fight, a battle royale."  

Maloof's rep, Howard Bragman told People magazine that Maloof gaining full custody is in the best interest of their kids.

"I think the court documents speak for themselves and we are not going to go into the gutter with Paul. We are going to fight this in the court of law where it belongs and do what's best for the children."  

According to an insider close to Maloof, Nassif doesn't care about anyone, but himself. 

"He keeps saying he's going to do what's best for the kids, but everything he does has been the best for him," the source told People magazine. "He's flailing and afraid and he rightfully should be. You don't do this to the kids. " 

For now, Maloof is "happy the kids are with her. She wants to do everything in her power to protect her kids."
