No matter how much they may fight on camera, all the ladies from the various Housewives shows managed to put their differences aside and pull together at the 2012 Bravo upfront event in NYC on April 4.  

All of them, that is, except the women from The Real Housewives of New York.

Judging from the new promo for Season 5, which kicks off on June 4, it should come as no surprise there’s no love lost among the six stars.

You could cut the tension with a knife as LuAnn de Lesseps walked the carpet alone, Sonja Morgan and Ramona Singer giddily walked along arm-in-arm and the three new cast members — Aviva Drescher, Carole Radziwill and Heather Thomson —  stuck by each other’s sides while keeping their distance from the rest.

Of course, we couldn’t resist asking Ramona what gives. As usual, she didn’t hold back.

Wetpaint Entertainment: What’s going on with the vibe in here tonight?

Ramona: I love seeing the girls from the O.C. and from Atlanta. Everyone is so much prettier in person!

What about the other girls from your own show?

Well, there’s one woman here I’m not even talking to!

Can you tell us who?

No, but if you watch this season, it won’t be hard to figure out.

You and Sonja seem as tight as ever. Can we expect more double trouble from you two this season?

Oh, sh*t, you have no idea!
