Dr. Phil is out to nail Kim Richards to the wall! The TV doc had a shocking sit down with the disgraced reality star after her arrest on April 16 -- and it makes for some pretty dramatic television!

Last Thursday, the Real Housewives of Beverly Hills star was arrested and charged for public intoxication at the Beverly Hilton Hotel. For the first time since the arrest, the 50-year-old, who has been to rehab several times for her drinking problem, is set to speak out in a tell-all interview that airs on Dr. Philon Tuesday.

In a sneak peek, the blonde somberly says, “I’m beating myself up over this. I poured a drink of vodka, and I thought ‘Oh my God, what have I done?’”

Unfortunately for Kim (but fortunately for us), the good doc ain't buying her remorseful act and questions her claims of being sober for three years. In front of three out of her four children, the 64-year-old personality says to the mom, "You are drunk in a bar, fighting with a cop, that is not good mothering."

“Is this an intervention?” Richards asks. After some tense moments, Kim says, “I’m sorry, I can’t.” Then the troubled star storms out of the room. Yikes!

Maybe this is just the "incomprehensible demoralization" Kim needs to get her act together!
