"I like her very much. She's a fun girl with a story to tell," Vanderpump told People at her luncheon benefiting the American Humane Association and the Hero Dog Awards at PUMP in West Hollywood.
"I can't tell you whether she's in the cast. If she was in the cast hypothetically, I think she would be a great addition."
Why Jayne would be a great fit?
"She's funny and she's risqué," Vanderpump explains. "But she's also got a great head on her shoulders."
Former Real Housewives of Orange County star Gretchen Rossi – who was also in attendance with her fiancé Slade Smiley shared a group photo in her Instagram page of herself with Jayne along with Lisa Rinna, Kyle Richards and Camille Grammer at the restaurant.
"With these beautiful ladies today @lisavanderpump 's event to help #stopyulinforever #comewalkwithusOct4th www.stopyulinforever.org," Rossi captioned the photo on Instagram.
When asked about Brandi Glanville, Vanderpump – who has had her ups and downs with the unfiltered blonde – says she has "no problem with [her]" and that "even if she had been on this season it wouldn’t really phase [her]".
When asked about Kim Richards' situation, Vanderpump shared her support.
"I'm sorry that Kim's not here because of the situation. That's the thing, but I think that her sobriety is more important than any reality show," Vanderpump said.
The 54-year-old also had kind words for Foster, who recently revealed she had a silicone leak from a breast implant rupture.
"I think it's been difficult and painful, but let's hope," Vanderpump said. "Let's pray that this is what it was and this is going to have a good result."
