'Vanderpump Rules' SURver Scuffle: Ariana Comes For Stassi -- 'This Bitch Actually Takes Pride in Being Ignorant'

On Monday night's episode, Stassi asked SUR hostess Billie Lee -- a transgender woman -- to appear on her "Straight Up with Stassi" podcast to help people "open their eyes to what the transgender community has to go through."

Billie agreed to do the interview, but before things got started, she told Stassi that Ariana Madix, Lala Kent and Scheana Marie had warned her about doing the sit-down.

"She did an episode on her podcast, and she was like, 'Well, I don't know why those people always make award shows into a thing about politics and race," Ariana told Billie in a flashback. "I hope you school Stassi's ass on her f-cking privilege because this bitch actually takes pride in being ignorant."

Back in May 2017, Stassi aired a podcast about the Academy Awards, where she said, "Everyone giving their impassioned speeches about race and all that stuff -- I'm like, why is it always just about African Americans? Why aren't the Asians being like, 'We're not represented'? Why aren't Native Americans and Latinos being like, 'We're not represented'? Why is it that it's always just that?" Stassi said she received backlash for the comments almost immediately.

"F-ck this," Stassi said in response to Ariana's warning. "You know what? Saying that I'm racist -- it's a whole other level of vindictiveness. I didn't articulate it properly, and I would actually just like you to go listen to it so you can make your own opinion. To shit on my podcast, to shit on my values, to shit on all of that makes me really upset."

Tearfully, Stassi added, "It's such a serious thing to say to someone. It's not just like, 'Oh, she's a bitch.' It's like a really f-cked up thing to say about someone."

"So like, [calling] me ignorant, fine," Stassi later told Bravo cams. "But Ariana saying that I'm prejudice, racist, anti any group of people -- I am not that at all. I love anyone unless you're an asshole."

Lisa Vanderpump came to Stassi's defense, saying during a confessional, "I've seen a lot of negative things come from Stassi Schroeder. I've seen her being a rude little bitch -- I've seen a lot of things -- but have I seen bigotry, racism, homophobia, discrimination? Absolutely not, and I would not tolerate it for a second."

Another upsetting exchange from Monday's episode occurred when Katie Maloney was told by Lisa's designer that her weight gain had gotten "out of control."

Katie and several SUR staffers were working an event honoring Lisa's new role as editor-in-chief of Beverly Hills Lifestyle Magazine when Katie offered Kevin Lee, Lisa's designer, some champagne. "What happened? You were much thinner than this," he said to her. "You gained a little bit of weight. You have to work on it, seriously."

"I am," Katie said, trying to maintain her composure.

"Seriously, I'm telling you as a friend," he replied. "It's out of control right now. I can tell." A few minutes later, Katie cried about it to Lisa.

"I've always thought he was amazing," Katie said tearfully. "I've just worked really hard in the last year. I just don't know why he felt comfortable saying that to me."

As always, Mama Lisa was there to comfort Katie, and in the process, revealed something about the SURver many viewers might not have known.

Back in 2009, Katie fell 25 feet through a skylight down a flight of stairs. Several of her bottom teeth were knocked out and her mouth had to be wired shut. The accident was quite serious and left Katie with a visible scar on the left side of her mouth, which Lisa and her husband, Ken Todd, offered to have fixed via plastic surgery.

Katie turned down the offer because "erasing that would have erased this pretty monumental moment in my life," she told Bravo cams. "I like my scar. I think it gives me character, and it's also a badge of honor, in some ways, that I went through something crazy, but I'm still here."

"Vanderpump Rules" airs Mondays at 9 p.m. on Bravo.
