Real Housewives of Beverly Hills star Kim Richards has entered rehab for the fourth time.
The move comes after the 50-year-old reality star was arrested on April 16 at the Beverly Hills Hotel for intoxication. She also stormed out of her interview with Dr. Phil last week, after she became increasingly uncomfortable with his questions about her recent arrest.
"Kim went to rehab finally because she got arrested, she humiliated her kids and she wants to avoid jail," a source tells People. "If the arrest hadn't happened she wouldn't be going to rehab; it would be business as usual. She's in denial that she has a problem."
ET has reached out for confirmation.
Richards has been to rehab three times. She completed her most recent stint in January 2012.
"A big part of all of this is that she is just stressed out," a family friend also tells the magazine about Kim's latest setback. "She is under a lot of pressure, especially because of Monty [her ex-husband, who’s battling stage IV cancer]."
According to the Beverly Hills Police Department, police were called around 1:30 a.m. on April 16 by hotel security because Richards was allegedly acting belligerent and refused to leave the restaurant inside the hotel. After getting taken into custody at 2 a.m., Richards allegedly dropped to the floor of the jail and started kicking an officer in the leg.
Richards explained to Dr. Phil about the incident, "I poured a drink of vodka, and I thought 'Oh my God, what have I done?' ... I knew what I had done. The whole night is my fault."
