Kim Richards Opens Up About Her Arrest To Dr. Phil

"Real Housewives of Beverly Hills" star Kim Richards is opening up about her arrest, saying the incident last week never would have happened if she did not drink.

"I was angry and frightened and I was scared. I knew what I had done," Richards told Dr. Phil, according to an early transcript obtained by People magazine, about the night of her arrest at the Beverly Hills Hotel. "The whole night is my fault. None of this would have happened if I didn’t drink."

Richards was arrested early Thursday morning after security at the hotel called the police because of a possible fight. The reality star locked herself in a bathroom at the establishment and police had to enter the bathroom and arrest her around 2 a.m., TheWrap noted.

"Hotel security requested to make a Private Persons Arrest and BHPD officers entered the restroom and took her into custody," Beverly Hills Police Department spokesman Lt. Lincoln Hoshino told Us Weekly. "She was passively resisting and she was taken into custody on Private Person Arrest."

She was ultimately charged with trespassing, resisting arrest, public intoxication and battery on a police officer, after she apparently kicked a cop while at the station.

Richards' sobriety was a main storyline in Season 5 of the Bravo reality show. While Lisa Rinna questioned whether Richards, who checked into rehab back in 2011, was still sober, the mother of four lashed out at her, denying that she had fallen off the wagon.
