It ain't over yet!

Though Taylor Armstrong's feud with Kim Richards was shown months ago, the women continue to rehash the drama on Thursday's Real Housewives of Beverly Hills reunion show.

Revisiting the scene in which Camille Grammer flipped during a dinner with the cast after overhearing a costar call her "insecure," Kim still says it was Amstrong who initiated the name-calling.

In a sneak peek from the reunion special -- hosted by Bravo's Andy Cohen -- Amstrong is still not willing to take the blame.

"Did you really think I was going to threaten her? I don't even know what 'Oklahoma' means," says Amstrong, who threatened to "go Oklahoma on [Kim]'s ass" at the time. "[Kim] had to learn some manners so we had to go outside. I've never laid a hand on anyone in my entire life. If that was taken in a way that makes it seems like I'm a violent person, then I misspoke."

As Kim trails off in response, Armstrong offers an aside to Kim's sister, Kyle.

"Should we talk about her state of mind at that table?" she asks, keeping in mind the cast's disastrous dinner party hosted by Grammer.

Says a fuming Armstrong: "She's about to push me there!"

As the siblings' rivalry came to a head on the show’s January 20 finale, a source tells the battle has been brewing for years.

"Kim's out of control. She was in rehab before too," an insider says of mom of four Kim. Adds another source: "Jealously isn't the root of their disagreements. It's tiring to watch Kim not make smart decisions and not learn from her mistakes. The family has been through hell!"

The Real Housewives of Beverly Hills reunion airs Thursday at 9 p.m. (EST) on Bravo.
