'RHONY' Ramona Singer, Bethenny Frankel Feud: Watch Season 7 Battle of the Alpha Dogs

Cue the drama! Real Housewives of New York might have started on a slow note last week, as fans were reintroduced to Bethenny Frankel and caught up with all the women of the Upper East Side, but during last night's all-new episode, the claws definitely came out, especially in the case of Frankel and her former friend Ramona Singer. While the girls traded in the streets of 5th Avenue for the Hamptons, they didn't leave their drama at the door, in fact, it was here that most of the drama started.

It seems that Frankel really rubbed Ramona the wrong way when she got to LuAnn's housewarming party. According to Radar Online, Frankel extended an invitation to get brunch with Sonja at the party, but didn't include anyone else who was present. Singer butted in, offended that Frankel was having a brunch of her own when she already had one planned.

In the clip that was posted to Bravo TV the girls get into a pretty heated discussion revolving around the incident.

"You're not going over: you're my guest and you're not going anywhere," the star told Morgan. However, it didn't seem like Frankel was putting up with Ramona's outburst, as she fired back at the housewife, saying, "What the hell was that? Are you really saying this out loud right now? What are you, out of your mind?"

"You don't invite my guest to your house unless you run it by my. That's not polite," Ramona told Bethenny, before Frankel said that she really didn't want to hang out with her former cast mate at all.

The conversation ended with Ramona trying to be the voice of reason, telling Bethenny, "You're acting weird. These are all my great friends and all I said is, 'Why would you have a brunch if I'm hosting a brunch?' You got offended and went crazy."

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