Lisa Vanderpump is paying Kyle Richards no mind, exclusively revealing to Us Weekly what she thinks of her former Real Housewives of Beverly Hills costar using her own husband Ken Todd's iconic "Goodbye Kyle" line against him. "I don't really kind of invest in it too much, to be honest," Vanderpump, 65, told Us of the drama while promoting the upcoming Vanderpump Rules reboot. Confirming she and Todd, 80, did see Richards, 56, at the Beverly Hills Hotel ahead of BravoCon, Vanderpump said she didn't hear her ex-friend's diss. (While on a BravoCon panel, Richards claimed she said "Goodbye Ken" as the couple exited the Los Angeles institution, just days before they both attended the three-day event in Las Vegas). "Actually, it's true. I didn't know she saw us," Vanderpump said in an exclusive interview with Us at her West Hollywood restaurant SUR on Thursday, November 20. Kyle Richards Slams LVP's 'Inconsiderate' Implications About Mauricio Split "We were in the Polo Lounge the other day, and it was crowded," she explained, acknowledging she did see Richards but "didn't want to get into it" because she was with a group of people. When asked if she heard Richards say "Goodbye Ken," Vanderpump said, "No, and I don't think anybody else did either, so whatever." Richards isn't the only former RHOBH frenemy whom the businesswoman has crossed paths with lately. "I had the luxury of sitting down opposite Lisa Rinna last night, just surprisingly, she was six feet away from me," Vanderpump recalled, sharing her immediate reaction was, "Hello. Oh no."

While she clashed with Rinna throughout her tenure, Vanderpump's friendship with Richards ended after she was accused of leaking a story to the press about Dorit Kemsley secretly rehoming Lucy Lucy Apple Juice, a pet she had adopted from Vanderpump Dogs. Vanderpump has no regrets about leaving Housewives - or choosing not to reunite with her former costars at BravoCon. "Now, the Housewives things, I normally just avoid, to be honest. I just say my job is to talk about Vanderpump Rules," she told Us, "and not to get involved in the minutiae with the Housewives." She continued, "Every time they meet, they have some kind of fight. That's not my thing, never was. When I was on Housewives, I always saw the funny side of things, until it wasn't and I was out." Lisa Vanderpump Says She Could Never Be Stranded With These 3 'RHOBH' Stars Vanderpump does, however, enjoy some of the women on her former franchise. "I love Garcelle [Beauvais]. Garcelle is just a decent human being," she shared. "I felt sad for her, the way she left, not on the most positive note. I think she's wonderful." "I see Camille [Meyer] occasionally in passing, and we always kind of embrace," Vanderpump added. "But when a group kind of all gets together and they try to come up with a story, I don't really respect that much." These days, the entrepreneur is staying booked and busy, starring on two of her own reality shows, Vanderpump Villa and Vanderpump Rules season 12, which makes its debut with a whole new cast on Tuesday, December 2. The group of servers and bartenders - including Venus Binkley, Jason Cohen, Shayne Davis, Chris Hahn, Angelica Jensen, Marcus Johnson, Audrey Lingle, Natalie Maguire, Demy Selem, and Kim Suarez - is ready to make their mark in an all-new, post-Scandoval era at SUR. "I was always very honest when I talked with production about not wanting to go down on a sinking ship," she told Us about the decision to reboot the reality TV series after 11 successful seasons. 'VPR' Cast Didn't Know the 'Extent' of Season 12 Recasting Plans "I felt that Vanderpump Rules was at its high, being nominated for Emmys. We had great ratings, but I felt like we told the story. And I thought at some point that it became a little bit more complicated to film," she explained, referring to Tom Sandoval's cheating fiasco with Raquel Leviss and Ariana Madix that ripped the once tight-knit group apart. "The dynamic was broken. It was shattered in so many ways. And I thought it was time to do something new." Vanderpump turned the cameras on several of her real-life SUR employees, noting she wanted the franchise to get back to basics, and the new cast didn't disappoint. "They're very, very outspoken. They want to get their opinion out," she teased. "They were so relaxed in front of the cameras. Also, they were available emotionally to share their vulnerabilities. There's some very interesting personal stories here." Vanderpump joked, "I like all of them very much, and I said to them, 'You know what, in eight years, you're all going to be a pain in my ass because that's the way I know the show's success." "They're lovely, they're excited, they're hungry, they're working here," she noted. "It's about the r
