Real Housewives of Beverly Hills star Kim Richards has entered rehab for the fourth time after her April 16 arrest and a contentious interview with Dr. Phil. Today, Dr. Phil weighed in on Richards' situation.

Richards' arrest came after she allegedly began acting belligerent in a restaurant at the Beverly Hills Hotel. After being 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 tried to explain her irrational behavior to Dr. Phil during an exclusive sit-down, airing tomorrow.

"The fans are very hard on me," Richards said. "[They say], 'You're a hoe. You're a liar. You are a drunk.' They were calling me all kinds of names, and I am an alcoholic. I've said that."

ET's Brooke Anderson asked Dr. Phil whether it would be wise for Richards to return for the show next season.

"According to her self-analysis, the trigger for this was reading a lot of tweets," Dr. Phil said. "If you're one of those people that feels the need to be loved by strangers, I'm not sure the public arena is the place you need to be. You need to inoculate yourself from that."

Richards RHOBH co-star Lisa Vanderpump agreed with Dr. Phil at the Race to Erase MS event over the weekend.

"I think she's battled these demons for years," Vanderpump said. "She kind of said it was the show, so clearly she shouldn't be part of it."

Prior to entering rehab, Richards walked out of her interview with Dr. Phil when things became too intense for her.

"I do not turn loose of my end of the rope when I'm dealing with someone that I think has a life-threatening, self-destructive bent," Dr. Phil said.
