The Ramona Singer vs. Heather Thomson tensions that have been boiling since the beginning of The Real Housewives of New York Season 5 finally exploded during Season 5, Episode 7: “Good Trip, Bad Fall.”

Heather attempted to make peace with Ramona during Aviva Drescher's anniversary party, but her plan backfired, sparking a huge fight where Ramona called her "phony" and a "liar," accusing her of talking behind Ramona's back and even having a fake smile.

We want to know: Whose side are you on in this spat? Do you think Ramona is totally overreacting, or is she right that Heather isn't as honest as she could be?

The Real Housewives of New York airs Mondays at 9 p.m. ET/PT on Bravo.
