After Sonja Morgan's odd behavior on last week's episode of "The Real Housewives of New York," the reality star admited that she might have gone a little too far in Atlantic City as she celebrated with Bethenny Frankel, LuAnn de Lesseps, Carole Radziwill, Heather Thomson, and Dorinda Medley. 

"It happened, I went off the rails," Morgan told Us Weekly at NBC Universal's event in New York City on Thursday, May 14. "I didn't what cheap booze I was drinking … but I hadn't eaten and I think with the bad mood in the group, the way it started off, you really shouldn't drink when you're with the wrong people in the wrong mood." 

It can be recalled that during the Atlantic City episode, the ladies shared a limo ride and argued for the duration of the ride, with some of them telling Morgan that she is "delusional" when it comes to her business ventures. Morgan had a conversation with Frankel, who advised her to slow down on the drinking and to seek help from a therapist.

"I'll always be close with Bethenny, LuAnn, and Ramona. But the thing about Bethenny is I think she's worried about me because of what the girls have told her," she said, referring to how the other ladies warned Frankel that Morgan is delusional. 

"She hasn't been around the last four years because she's been busy raising Bryn and dealing with her marriage. If you listen to what the girls say, it's all lies — especially what Heather's saying, total lies! She's told so many lies in 15 minutes," she added. 

In the episode, Thomson repeatedly said that Morgan's ventures are all made up. 

"I don't have to lie about my castmates or knock their businesses or their hard-partying ways to be relevant and that makes me feel really secure and happy with myself, where I go," the Bravo star said.

"The Real Housewives of New York" airs Tuesdays at 9 p.m. on Bravo.
