Did she or didn't she?
On Monday's episode of The Real Housewives of Beverly Hills
, Kyle and Kim Richards claimed that Lisa Vanderpump "fake-fainted" while training with partner Gleb Savchenko on last season's Dancing with the Stars
"Some people just aren't cut out for fake faints," said former child star Kim, 49, who joined her sister at her home to watch Vanderpump, 53, dance on the show. Instead, they watched her collapse dramatically to the floor while in the midst of rehearsal.
"Lisa wanted out," said Kyle, 44, who has been feuding
with her former friend.
While Kim may not need an acting coach to teach her to faint, she did need a dog trainer to help her with her troublesome pooch, Kingsley.
"He's eaten thousands of dollars of shoes," she said, before turning emotional. "This has been a transition time in my sobriety, and this dog has been there for me. People come and go, but my dog is always there."
The same could be said for David Foster, the Grammy-winning music producer, who stood by wife Yolanda H. Foster as she battled Lyme disease.
"I think Lyme disease showed me I could be a good husband," said David, who accompanied his wife to the hospital where she had a port removed from her heart.
"I was losing brain function," revealed Yolanda, 49. "[With Lyme disease,] you look great from the outside, but you're dying on the inside."
Meanwhile, Brandi Glanville moved into her new home with the help of her mother.
"No matter how old you are, you always need your mommy," the 40-year-old said. "My mom is everyone's rock."
Kyle Richards had the two newest housewives – former Miss Puerto Rico Joyce Giraud and Carlton Gebbia – over for lunch, while Vanderpump, who is in the midst of opening a new gay bar, PUMP, hosted Glanville and Foster.
Both groups served up gossip as the main dish.
Foster didn't hold back when she was asked about her status with Richards. "I'm not in a better place with the woman who called me a liar," she said. "She really doesn't have any girlfriends."
At Richards's outdoor lunch, the killing of a bee had self-proclaimed witch
Gebbia, 40, buzzing. She felt the insect should have been relocated rather than squashed.
"Why would you do such an awful thing?" Gebbia asked.
"I'm a bee-murderer accomplice," joked Richards, who is allergic to bees.
But when Giraud, 38, began telling the ladies about how she met her husband, it was Gebbia who delivered some stinging words.
"The story's been going on for a while, and I'm wondering when we're going to get to the end of it," she said.
