Ariana Madix and Tom Sandoval are widely known as one of the more sane couples of Vanderpump Rules but on next week's episode of the Bravo TV reality series, the couple will be seen engaging in an ugly war of words.

In a sneak peek at the upcoming episode, Sandoval is seen telling Madix and Lala Kent that he'd like to be more involved in Madix's upcoming cocktail book. Unfortunately, Madix isn't at all on board with his idea.

"You're not going to be the face and you're not going to take attention away from me. Don't f**king roll your eyes you little f**king b***h. I just saw you roll your eyes over there. You can't even be a part of this conversation like a normal person?" Madix asks.

"Ariana, do you understand that literally Jax, Katie, Scheana, everybody came up to me and they're like, 'Why is Ariana doing a cocktail book and not you?'" Sandoval responds.

"Really? I've been bartending for 10 years at some of the busiest and most well known places in the country," Madix points out.

"...with a reputation as Grumpy Cat," Sandoval continues.

"Somebody is a Bitter Betty," Madix fires back.

And it gets worse.
