It's one action-packed dramatic moment after the next in The Real Housewives of Beverly Hills' midseason tease

Denise Richards and Camille Grammer Butt Heads in Heated Trailer for the Rest of RHOBH Season 9

The drama on season 9 of The Real Housewives of Beverly Hills is just getting started.

PEOPLE has the exclusive premiere of the hit Bravo show’s midseason trailer, and Lisa Vanderpump and Kyle Richards aren’t the only costars feuding.

Toward the clip’s end, Denise Richards and Camille Grammer get in each other’s faces for a tense argument. “You know,” Denise, 48, tells Grammer — who quickly says, “No I don’t know, Denise, so back off!”

That doesn’t sit well with the Wild Things actress. “You f—ing back off!” she screams at Grammer, 50.

Just what they’re fighting about remains to be seen. But from the footage shown in the trailer, it’s just one of the tough moments Grammer has coming up.

The new few episodes will document the highs and lows of the O.G. Beverly Hills Housewife’s past year: from her romantic Hawaiian wedding to husband David C. Meyer to the horrific loss she experienced in November when the Woolsey Fire destroyer her Malibu home.

“It’s like some horror movie,” she says as she tours the wreckage. “I’ve got to get out of here.”

And Vanderpump remains estranged from most of her RHOBH castmates in the wake of the #PuppyGate scandal.

“You don’t treat people you love like that,” Vanderpump, 58, tells Denise, who assures the SUR restauranteur, “Those women still love you!”

Though Vanderpump’s not talking to Kyle, Kyle, 50, is certainly talking about Vanderpump. “She’s going to make herself the victim,” Kyle says. “She’s going to turn it all around so that everyone else is wrong.”

“It’s gonna get nasty,” Grammer warns.

It’s not like Kyle and the rest of the group are staying a united front. She, Teddi Mellencamp Arroyave, Dorit Kemsley, and Erika Girardi all bicker throughout the midseason trailer.

“Are you trying to push me out?” Girardi, 47, asks Kyle and Mellencamp Arroyave, 37, before storming away. “You guys want to make up s—? Good.”

If that weren’t enough, former Housewife Brandi Glanville returns to stir the pot.

All in all, it looks like one action-packed dramatic moment after the next. But there will be plenty of laughs, too, including some recent celebrations, like the opening of Vanderpump’s cocktail garden at Las Vegas’ Caesars Palace on March 30.
