The explosive account of what happened on the night of April 16 has emerged in an emotional interview Richards has given to Dr Phil that will air tomorrow. The Daily Mail Online has learned exclusive details from the session during which Richards – who has battled with alcoholism for years – told how she dramatically fell off the wagon. Dr Phil: If you’re an alcoholic that has fallen off the wagon, you’re at your daughter’s house and all of a sudden you’re in there pouring a drink, and then you roll into a bar at midnight, what, you’re already drunk when you get there, why, why would you not order a drink? Kim: Because… . Dr Phil: Why would you go to a bar if you’re not going to order a drink? Why not go to a pancake house….you could have gone to IHOP?! Kim: Because I went there, because I was feeling the drink, and I didn’t want to drive anymore. and I pulled in so I wouldn’t be on the road. And I pulled in there because that’s a safe place for me. Dr Phil: You went to a bar! Kim: That’s where I usually go. And I've been going there for years. Dr Phil: You could have got a room, you could have gone into the lobby. Kim: I was just gonna sit down for a few minutes and just— . Dr Phil: In a bar! She says she pulled in to the Beverly Hills Hotel because she felt the glass of vodka she drank at her daughter Brooke's house kick in. She knew she would be comfortable at the hotel. He ex-in laws (she was married to Gregg Davis, son of mogul Marvin Davis) owned the hotel and she's been going there since she was a little girl. But soon after arriving at the famed hotel, Richards was asked to leave by the maître d' at The Polo Lounge after he claimed the wobbly Real Housewife began harassing two strangers at the bar. She had earlier been asked to return to her own table after approaching the couple, but when she refused, a furious row erupted and hotel security was called. The night ended with Richards' well publicized arrest. The former child star turned Real Housewife claims she drove to the Beverly Hills Hotel at midnight on April 16 after drinking a large glass of vodka. Richards says she pulled into the hotel on her way home because she saw it as a 'comfortable, familiar' place and felt the alcohol taking affect. Astonishingly, the mom-of-four insists she didn't head straight to the hotel bar with the intention of buying more alcohol. She told Dr. Phil she pulled into the hotel because she felt the alcohol was unexpectedly hitting her. Before entering the hotel she sat in the driveway for a while and cried. She went into the Polo Lounge and headed to a table in the corner where she always sits. There were some people at the table and she walked over and began chatting with them when the maître d' - who she says she didn't know - asked her to return to her own table. Richards said she didn't because the woman she was talking to said she could stay. Kim: I started to drive home, and it was about when I hit the hotel, that I started to feel it. So I pulled in because I'm comfortable there, I've been going there since I'm a little girl…. Dr. Phil: Did you order a drink when you got there? Kim: I did not. The bar was closed. It was empty.  I do know that when he mentioned the word trespassing. Dr. Phil: Who said trespassing to you? Kim: The waiter. He said you know, 'If you don't leave we're going to call the police for trespassing.' Dr. Phil: All of this is because you poured yourself. You said – . Kim: Oh no, it was a good size. Dr. Phil: A two inch drink? Kim: Oh yeah. Dr. Phil: Was this in a five gallon paint can? What? Kim: No. It was just in a glass. Dr. Phil: Let's talk about the common sensibility of your story. Let's assume this is somebody else. Okay and I leave and I'm starting to feel it so I swing into the Beverly Hills Hotel and I go into the Polo and I'm obviously impaired cause there's somebody over there that I don't know from Adam but I think I do. Kim: Right. Dr. Phil: And I go over to their table and start talking to them and I'm just chatting them up but it's enough that the maitre d' in a bar, which is a social scene comes over and says – . Kim: When people drink – . Dr. Phil: 'You need to go back over to your table here because…' Kim: Right. Dr. Phil: But then it gets to the point that he comes back and says, 'No you're trespassing. You need to not only go back to your table, you need to leave this establishment.' Kim: Right. Dr. Phil: Were you loud, were you obnoxious, were you crazy? Admitting that the night was a little foggy, Richards said she went to talk to the stranger because she thought she knew her. She claims she did not have a drink at the hotel as the bar was shut but admitted she didn't remember much. But when the maître d' told her if she didn't leave he was going to call the police for trespassing she got bent out of shape. Since she first appeared on the hit reality show in 2010, Richards' sobriety has been her major storyline, with her recent relapse as the driving force between Kim and sister Kyle's distant relationship.
