The claws come -- again -- on part two of The Real Housewives of New York reunion (airing tonight on Bravo).

After Jill Zarin denied she was jealous of Bethenny Frankel for getting her own reality show, Ramona Singer calls out Zarin, 46, claiming that she asked her not to film any scenes with Frankel, 39, so Frankel couldn't "ride on our coattails."

"Are you KIDDING me?!" Zarin snaps. "You are such a liar!"

Kelly Bensimon then chimes in, saying that Frankel asked the other castmates not to film with her last season.

"Yeah," Frankel admits, "I didn't want to film with you."

In the end, Zarin apologies for her behavior, telling Frankel: "It was wrong."
