Nearly one year after their bitter, public feud, Real Housewives of Beverly Hills' Lisa VanderPump and her former permanent houseguest, Cedric Martinez, have reunited.
As a preview clip from Monday's episode shows, Martinez crashes VanderPump's launch party for her new Los Angeles eatery, Sur, uninvited, leading the housewife -- and her husband Ken Todd -- to angrily kick him out during a fiery confrontation.
"I just came to congratulate you. How are you? So good to see you," Martinez -- who lived at the family's sprawling Beverly Hills mansion rent-free for over a year -- chirps when VanderPump asked who invited him to the bash.
"I have no idea what you're doing here. What do you want from me that you haven't had already?" an icy VanderPump snaps back. "It's not the right time because this is my party and you're not invited. I don't wish you any harm. Worse than that: I don't wish you anything at all. I want you to leave."
When Martinez continues to stick around and hobnob with fellow Housewives Adrienne Maloof and Kyle Richards, VanderPump is steamed. "I can't believe the gall of Cedric to turn up," she says. "It's very difficult for me, there's a lot of pain."
VanderPump and Todd opened up to Us Weekly in February after last season's reunion show, explaining that Martinez snapped when Todd confronted him about his laziness.
Explains Todd: "[Cedric] said, 'I'm not asking for money, but I haven't got any, and I've been offered to sell my story to magazines. I can say anything I want." He also tells Us that Martinez suggested during the spat that he could get violent. "He said, 'The last time I was this angry, I stabbed my father,'" says Todd, who says he filed a police report after their interaction.
(Denying the couple's claims, Martinez tells Us, "This is what they do when they get bored.")
Watch more of VanderPump's run-in with Martinez in the clip above before the all-new episode of The Real Housewives of Beverly Hills airs Monday at 9 p.m. (EST) on Bravo.
