Kathryn Edwards and Erika Girardi have been members of the "Real Housewives of Beverly Hills" cast for a just few short months, but they're right in the thick of some serious drama — with one another. The "Real Housewives" rookies butted heads in Season 6, episode 15, after a bit of private gossip turned public and hurt the feelings of Lisa Vanderpump.

Erika invited her co-stars over for a dinner party at her lavish home, giving them the opportunity to meet her husband, Tom Girardi, for the first time. As with a majority of "Real Housewives" dinner parties — especially in this franchise — the evening doesn't go as planned. The ladies arrive, say their pleasantries and take their seats. The food hits the table and the conversation begins, but is a little too off-color for Erika's conservative husband. Kathryn and Lisa bring up the lingering drama from episode 14, which stems from Erika claiming Lisa was manipulative. The pair joke about the situation, but Erika is far from laughing. In fact, she is mortified that anyone would broach such a subject in Tom's presence. 

The conversation persists, dominated mostly by Kathryn. Erika and Tom attempt to interject, but are shut down. Lisa V. gets some answers about the drama and decides to leave before it escalates any further. With that, Lisa Rinna and Kathryn decide to part as well. Erika is visibly upset by the direction of the dinner party — especially the following day.

She and Kyle Richards meet up for an afternoon of pickle ball (which is a real sport, according to Mauricio Umansky). The ladies take a break from their game to chat about the evening's events. Erika reveals to Kyle that her own husband wasn't speaking to her afterward, which only furthered her discontent. 

Tensions really came to a boil when Erika, Kathryn and the rest of the "RHOBH" crew reunited days later to build houses for Habitat for Humanity. Erika begins her assignment — painting a house for a family in need — near Lisa V., who is being cordial but not shying away from web jokes. Erika is clearly not amused, but hangs in as long as she can. Kyle makes one final crack about spiders that sends her over the edge. She steps away and decides to join Eileen Davidson and Lisa R. instead. Naturally, it's not long before the topic comes up again. Erika reveals to Eileen what a strain Kathryn has put on their relationship as well as her relationship with Lisa V., which inspires the "Days of Our Lives" star to take a stand. She suggests the women come face to face once more and finally confront the real issues.

Eileen poses a question about the situation, hoping it will open the floor to constructive conversation. Instead, it ignites a screaming match. Erika dominates the conversation, putting Kathryn in her place about sharing details from private conversations. Kathryn stands by her belief that their conversation was not off the record, adding that she didn't see Erika saying Lisa V. tends to "spin a web" as a negative. 

While this drama has dominated much of the last two episodes, next week will take a new direction. Previews for the show suggest Kim Richards will come up once more, which always causes quite a stir.

"RHOBH" airs Tuesdays at 9 p.m. EST on Bravo.
