Whatever you think of Ramona Singer, it's pretty clear that Heather Thomson calling her "crazy" — and not in a joking way — to Mario Singer's face on Real Housewives of New York Season 5, Episode 11: “This Party Is Toast” was not the smoothest move.

It looks like Mario steps up to defend his wife on Episode 12 (airing August 20). In this preview of the episode, he gets into it with Heather in a big way. And if that's not drama enough, Heather then gets pissed at Aviva Drescher for not defending her.

Check it out below.
