'She's more manipulative than anybody': Lisa Rinna accuses Yolanda Foster of using Lyme disease to her advantage on RHOBH

Lisa Rinna during a fierce attack on Tuesday's episode of The Real Housewives Of Beverly Hills claimed that that her castmates were being 'manipulated' by unwell Yolanda Foster.

The 52-year-old former soap opera star told her friend Eileen Davidson that she believes Foster has been using her Lyme disease to her own advantage.

'I believe she is sick, but I think we are being painted into a corner because of that sickness,' said Lisa coldly as the friends met at the beach.

Gut feeling: Lisa Rinna accused Yolanda Foster of using her Lyme disease to her advantage on Tuesday's episode of The Real Housewives Of Beverly Hills

'I just feel like maybe she uses that sickness to her advantage in a lot of ways. Get a lot of sympathy. And I know that she does't want a lot of pity - but boy,' Lisa added.

'Nobody doubts that she is not well, however, but I think that there is a component of her head not connecting to her heart and there is something emotionally going on that is not being dealt with.

'You know what I think? I think there might be a bigger spiderweb, a bigger manipulation, when it comes to Yolanda.

'She's the only person I know on the planet that has gone to bed for 10 months,' Rinna said.

Eileen told the cameras that she could not believe what she was hearing from Lisa.

'Nobody has to agree with me at all. My gut feeling, as much as I want to love Yolanda and be her best friend, my gut says run for the f***ing hills, lady.

'She scares the s*** out of me because I think she's more manipulative than anybody,' she added.

Lisa then told soap star Eileen that she was 'having trust issues with everyone right now. They are through the f***ing roof.'

'I can see this,' Eileen told her.

Trust issues: Lisa said she has trust issues and Eileen agreed

Lisa also told Eileen that she had been manipulated by Lisa Vanderpump and Kyle Richards over Yolanda.

'I really tried to be Lisa's cheerleader, because I love her in so many ways, but she really has done some things and I want to be honest about it now because I feel like I was protecting her and I've been protecting her,' said Rinna.

'I've kept quiet because I was hoping to protect a friendship. I do think that Lisa's been manipulative, but I think a lot of people have been manipulative.

'Both Lisa and Kyle talked plenty about Yolanda and whether she had Munchausen or whether she was faking it. And they sent pictures back and forth to each other, giggling. Absolutely,' she claimed.

Earlier newcomer Erika Girardi threw a dinner party for the ladies to meet her husband Tom and it did not go well.

Things got off to a rocky start as Lisa Rinna and Erika were both in leopard-print dresses.

'I am usually the only one in leopard so maybe these girls are encroaching on my territory,' Lisa told the cameras.

Erika told the ladies that Yolanda could not be there as she was feeling under the weather.

Things went south as Erika and Kathryn got into a loud shouting match that started when Kathryn claimed she could convince anyone to take her point of view.

'I'm able to turn it around and change the argument and convince someone that's not even what they started saying,' she told them over dinner.

Lisa called her a 's**stirrer' and Kathryn defended herself saying: 'It's called having a sense of humor, try it on.'

'There are manners and a way to handle yourself in another person's home. Kathryn is pushing it here,' an unimpressed Lisa Rinna told the cameras after Kathryn joked she needed to eat some bread sticks.

Kathryn continued to rub the guests up the wrong way with her aggressive behavior and opinions and trying to dominate every conversation.

And she would not accept it when Erika told her that it took some time for her to open up to new people.

'What the f***. Just relax girl, let us get to know you. You don;t have to hit us over the head with your personality,' an unimpressed Erika told the cameras.

Kathryn then said that when someone closed themselves off to her she made it her mission to get close to them.

'I am trying to talk your language, give me something,' Kathryn said as Lisa Rinna reprimanded her and told her that she talks a lot.

'Kathryn is talking a lot and she is loud and she is aggressive, I would like to level Kathryn at this point, tape would work too,' Lisa told the cameras.

Erika told them she was 'a cautious girl' when she was getting to know someone.

'I can't believe these people are sitting in my home and treating me this way,' said Erika.

And things did not get any better when Lisa Vanderpump brought up criticism that Erika had made about her to Kathryn, who told Erika not to roll her eyes at her.

'Why are you yelling at me in my own home? What are you being so aggressive?' Erika asked defensively.

Kathryn told her that she did not feel bad but that there was a misunderstanding.

'This is really rude. I would not come to someone's home and meet their husband for the first time and act like a f***ing ass,' said Kathryn as her husband Tom asked in amazement 'Do you guys really do this all the time?'

Lisa Rinna hid behind her napkin as the atmosphere continued to grow colder and colder and Lisa Vanderpump left for another event. 

'This is not the dinner party I had in mind and I am totally embarrassed for me and my husband,' said Erika.

'I would not go to someone's home and start s***, I was raised better than that and I was hoping these women were too. Apparently not. I would rate tonight as negative five, I will never be doing this again,' added the showgirl.

Worst party ever: Erika vowed to never host another party for the ladies

Kyle Richards and the ladies then got together to help out at a Habitat For Humanity home building project in the Watts area of Los Angeles.

Lisa Vanderpump kept the jokes going with Erika about her criticisms as the women got down to some hard labour.

But eventually even Lisa had to urge the women to drop it as Erika was not amused and vented to Lisa Rinna about the dinner party.

Kathryn was then confronted about why she told Lisa Vanderpump about Erika's comments.

Erika told her that she now could not have a good relationship with Lisa Vanderpump and bashed her for her behavior at the dinner party.

'Kathryn is full of s***, are you kidding me? Kathryn played the tattle-tail game,' Lisa Rinna told the cameras.

Kathryn ended up apologizing and the women hugged out their issues.
