The cause behind The Real Housewives Of Beverly Hills star, Lisa Vaderpump is squabbling with her cast-members.

A lot of fusses started to swirl up around Lisa Vanderpump when she apparently decided to skip out Andy Cohen’s baby shower last weekend. While the 58-year-old British star claims a business meeting in Las Vegas kept her away from the mizzle, Kyle Richards says she only missed out because she was looking to “get paid to attend” another party.

But according to various sources its been revealed that there is much more to this drama than meets the eye. Allegedly the real reason behind Vanderpump’s feud with her co-stars is reportedly linked to Dorit Kemsley’s dog.

Now why are so many of the housewives from different cities coming after @LisaVanderpump?! This is making them all look PATHETIC. This will bring the franchise down. It makes them look like a bunch of insecure women. #RHOBH #RHOA #RHONY @Andy — Redbandit (@Redbandit0202) February 2, 2019

Inside sources claim that Vanderpump rule’s star wants nothing to do with her Real Housewives of Beverly Hills fellow-stars because of rumors about a dog Kemsley reportedly gave up for adoption Twitter. According to Daily Mail, Vanderpump started the tittle-tattle about how Kemsley sanctioned a dog from the Vanderpump Dog Foundation, only to give up the pooch to another shelter a few days later.

After the hearsays were leaked to the media, Vanderpump instead defended Kemsley so that it would look like she was rather a pacifier. Sources, however, asserts that Vanderpump’s co-stars believe she planted the rumors with various publishers just to make Kemsley look bad. In reality, Kemsley found another home for the dog after the pet went mongrel and bit one of her family members.

According to her, the mutt didn’t concur with new family either and they also gave up on the dog essentially handing it over to another shade.

Insiders also forwarded--Kemsley called Vanderpump after she decided to give up the dog and that she was “heartbroken” by the entire ball game. Vanderpump allegedly told Kemsley not to brood over it and assured her that she was doing the right thing.

“She gave it to somebody who really wanted the dog, who assured her it was going to a loving home, and that’s what Dorit thought. She would not drop the dog off at a shelter,” Vanderpump confessed in a later interview.

The melodrama between Vanderpump and her co-stars had only got worse after Cohen’s party. Following the shower, Kyle Richards told TMZ that Vanderpump’s absence had created drama and even lampooned her by saying “they should have paid her to attend the event” which later only deemed to insult Vanderpump.

Mrs. Todd then immediately hit back by accusing Richards of calling her a “bitch” to which Kyle later explicated that she was not talking about Lisa Vanderpump in her original comments at all.

Along with all these stories including pup and the word, b****h, another equally popular theory also qualifies as to why Vanderpump is dissing out her fellow housewives. And this assumption no 2 is directly related to Vanderpump’s hubby, Ken Todd. It was purported--Kyle Richards and Todd were involved in a heated dispute at the Beverly Hills home which Ken shares with his wife, Lisa.

Months after rumors first began foaming, in regard to the fight between Kyle and Ken, which resulted in Kyle allegedly being barred from Villa Rosa, new details were also being revealed about the intensity of their dispute.

“There is a big fight that happens this season at Lisa Vanderpump’s house (shown in the trailer) where the other ladies felt Ken got too close to Kyle as they got into an argument,” a source reported to Hollywood Life on January 10. “It was so bad and scary for everyone that security had to get involved, which led to Kyle being kicked out of Villa Rosa, the home Lisa shares with Ken.”

And later when people watched for themselves in the trailer for season 9 of RHOBH—Ken yelling at Kyle, “You’re a f***king liar. Goodbye Kyle”, the hyped speculation only grew more and more towards the probable cause behind Vanderpump quitting the show.

While the exact cause of Ken and Kyle’s fight is yet to be unveiled, it has been rumored that it happened after Kyle ostensibly accused Lisa of leaking a negative story about their castmate Dorit Kemsley to the press. An accusation Lisa has been denying from the very beginning.

According to prior reports, Kyle and Ken’s contention was one of the main reasons Lisa found herself on the outs with the RHOBH cast, aside from the series’ latest star, Denise Richards.

As the insider explained, the wives were horrified by Ken’s treatment of Kyle and even blamed Lisa for letting slide her husband’s verbal abuse. “All of the other wives came to Kyle’s defense quickly and have reminded her of this incident as she’s pondered reaching out to Lisa.

Kyle always has a soft spot in her heart for Lisa and is a very forgiving person, but the other ladies feel this incident took things way too far and have no interest in forgiving her,” the insider resumed. “This incident is the cause of the wives not being able to move past their feelings for Lisa. Everyone had Kyle’s back and continues to do so. The fight is like nothing you’ve ever seen on Beverly Hills before.”

As fans well know, Lisa went through hard times before she commenced the production on season nine following the tragic suicide of her brother, Mark Vanderpump. Now, several months after the setback, Lisa is ready to start 2019 off on a fresh foot.

And although she faced backlash suggesting she may leave The Real Housewives of Beverly Hills due to the drama she faced throughout filming on season nine, the insider said she’s now in a much better spot.

“It seems like now that RHOBH is getting closer to the premiere date, she’s a bit calmer rather than anxious to see how everything shakes out,” the source continued.

“Lisa knows her value and worth as a cast member and is in a completely different place now than when she filmed a good chunk of it in the fall. Friends and staff members alike see a true shift in her as she moves forward. She seems a lot happier and in a much better place right now.”
