Threats, Backstabbing & More! Watch The Explosive 'RHONY' Reunion Preview

The claws are out on this season's reunion show for The Real Housewives of New York City, which is set to air Wednesday, September 7.

During the two-minute teaser video, plenty of name-calling and backstabbing, but nothing as bad as Sonja Morgan accusing costar Dorinda Medley of doing drugs.

"Why are you insinuating that you know I do drugs? That's a horrible thing," Medley says in the clip, exasperated.

Without missing a beat, Morgan shoots back, "Everybody knows you do drugs." Gasp!

But there's plenty more drama in store — for all the 'Wives — and it sounds like a lot of it could come from fed-up Morgan.

Leading up to their group sit-down, host Andy Cohen asks the RHONY ladies if they're nervous for what's to come.

"I have dirt on all the girls. I just hope I don't go there," Morgan reveals. "But I'm starting to, after all these years, have resentment."

And of course, Bethenny Frankel and LuAnn de Lesseps go head-to-head following their blowout fight during the season's finale, with plenty of evil stares and harsh words exchanged.

Tune into Part 1 of The Real Housewives of New York City season 8 reunion on Wednesday, September 7, at 9 p.m. ET, on Bravo.
