Next Week on 'Audrina': The Claws Come Out When A's Mom and Sister are in NYC for Fashion Week

Audrina Patridge, you should have known better.

From the inception of VH1's new reality show, "Audrina," viewers have seen the love/hate, but mostly hate, relationship between her mother Lynn and sister Casey. From squabbles at the dinner table, to name-calling, these ladies really know how to butt heads.

So last week when Audrina, former star of "The Hills," invited both women to join her at Fashion Week in NYC, we expected the best worst.

Judging from a preview of next week's episode, the attempt to bring the women together doesn't go as planned. A dream weekend for Audrina turns into a nightmare when Lynn and Casey break into a full fledged catfight at a restaurant. Will these infamous feuders ever kiss and make up?

See what happens this Sunday at 9/8c on VH1.
