Rule No. 1 of the Real Housewives franchise? You don't break the girl code.
But that's exactly what seems to have happened on The Real Housewives of Orange County, as all of the ladies get into a heated argument at dinner in Tahiti when Heather Dubrow confronts Vicki Gunvalson, Shannon Beador and Tamra Judge for calling her "a horrible person" for being friends with Meghan King Edmonds AND her husband Jimmy's ex-wife, Allison. Oh snap!
We have your exclusive first look at the intense showdown, which finds the Housewives arguing over the "girl code," as well as Shannon calling Tamra out for running to Heather. "Tamra, at this point, can I not have a fun night with you?" Shannon asks, clearly forgetting she's on a Bravo reality TV show.
