When Bravo confirmed last fall that Bethenny Frankel would be returning to her old stomping ground for season seven of The Real Housewives of New York City, fans knew that it was going to get messy. Frankel is hardly a treat to deal with and the rest of the cast need precious little to motivate them to fight. Apparently little North West wasn't the only one disrupting things for NYFW because a public argument between Frankel and Ramona Singer during Sonja Morgan's show had everyone talking.

According to a report by Radar Online, "Ramona and Bethenny were fighting openly in public at the event. They didn't seem to care who was watching. You could hear their voices even though the room was crowded and loud. They were waving their hands around and up in each others' faces. The fight lasted for a good 20 minutes. Everyone was watching and whispering and wondering what was going on," explained the source.

It doesn't take that much to get Singer going and it seems that after years of running in the same circles, Frankel would know exactly what buttons to push to make her cast mate lose it. From what we're hearing, Frankel's return to the reality show hasn't sat well with the rest of the cast. In fact at the event that was mentioned above, the ladies were all but ignoring her in favor of supporting Singer. Not that Frankel seems to care much because she doesn't seem to have much use for them either.

Bravo obviously brought Frankel back into the fold to really shake things up and it has worked from their standpoint. But will her arrival bring back some of the old RHONY viewers that stopped watching years ago? Tell us your thoughts in the comments below!
