The drama among the Real Housewives of Beverly Hills has reached a boiling point for Lisa Vanderpump, who is refusing to return to the show after her co-stars accused her of leaking stories to the press.

A Bravo executive has told DailyMail.com that the 58-year-old reality star wants nothing to do with her cast after they shunned her following reports Dorit Kemsley abandoned one of Lisa's rescue dogs at a shelter.

'It's all-out war on the Real Housewives of Beverly Hills and we cannot get Lisa to film with the entire cast,' the source said.

'She's said enough of the b****iness and called time on filming with the other women.

'She will film at her home, restaurants, and charity endeavors and has filmed individually with some of the cast members, but as of now her future on the show is uncertain.

'We'd like her to come back, work things out and film with the entire cast but she's said no.'

RHOBH vet Lisa Vanderpump has refused to film the newest season of the Bravo reality show with her co-stars after they allegedly turned against her, a source told DailyMail.com. Her co-starRinna has stated that she has 'no beef' with Vanderpump, but has continued to make barbed remarks

Bad blood: Vanderpump was shunned by her cast after they accused her of leaking a story about Dorit Kemsley abandoning one of her rescue dogs at a shelter

The British-born restaurateur, who has been part of the series since 2010, has not shown up to shoot with the rest of the cast for six weeks, according to co-star Lisa Rinna, 55, who has publicly criticized her isolation.

The network source revealed that Lisa has distanced herself from the housewives after they accused her of being responsible for a RadarOnline story about Dorit in September, even after the outlet denied she was the source.

'It all started when Dorit Kemsley dumped not one, but two of her dogs that she had adopted from Vanderpump Dogs,' the source said.

'She returned one to Lisa and then the next dog she was given was discovered in a kill shelter. A kill shelter!'

RadarOnline cited an anonymous source stating Kemsley left a rescue dog at a shelter after it allegedly 'nipped' one of her kids.

The outlet also claimed Lisa, an avid dog lover, was 'furious' at her co-star upon learning the news, but she later told TMZ there was no bad blood between the pair.

'Lisa and her team tried to keep the story out of the press, but somehow it leaked to RadarOnline and Lisa even went so far as to do an interview with TMZ to defend Dorit even though Dorit was clearly in the wrong,' the source said.

'It's great drama for the show as, rather than the women turning on Dorit for abandoning two dogs, they've accused Lisa of leaking stories to the press about it and that's the storyline for the season.

Vanderpump was even a no-show at fellow housewife Camille Grammer's wedding this weekend and it is unclear whether she will ever reconcile with the cast

'It's beyond absurd - Dorit discards the dogs like trash, but the women shun Lisa and accuse her of leaking the story to the press. The women on our cast clearly have their priorities wrong.'

'Lisa has begged the women to believe her, but they won't. The boss of Radar even came out publicly and defended her saying she wasn't the source but the women still don't believe her.'

Radar's boss Dylan Howard responded to the claims in a separate article saying: 'I can say unequivocally that Lisa has never been an anonymous source to the site' - but his comments apparently failed to placate the housewives.

Since then, things have been far from friendly between Lisa and the cast members, who have accused her of blowing them off.

Rinna and Erika Jayne Girardi took to Instagram live last month to mock Lisa claiming they were 'sequestered' in a room after a unnamed castmate refused to take photos with them.

The Melrose Place alum, who has been the most outspoken on the drama, even went as far to make a barbed joke for Lisa's birthday, September 15, on Twitter.

Rinna shared a photo of cupcakes topped with various prescription pills saying: 'Oh Happy Belated Birthday @LisaVanderpump I made you some special cupcakes for your special day!'

The tweet was later deleted.

'Viewers will see that Lisa Rinna has also been on the attack and some may argue is the cruelest. She tweeted [the photo] only months after Lisa's brother committed suicide from a drug overdose. She was called out over it and deleted it.

'She then posted on social about a cast member refusing to shoot with everyone and now she's responding to fan comments on Instagram about Lisa Vanderpump not doing her job,' the source added.

Rinna also slammed Lisa on a Bravo fan's Instagram account on Tuesday saying: 'Why hasn't Lvp filmed with us for over 6 weeks? I have no beef with her. Who does that? Who doesn't show up to work?'

When the fan suggested Vanderpump wasn't filming because she was still in mourning after her brother's suicide in May, she dismissed it saying she kept working after her own father's death.

'I have great empathy and I have been there. If you sign up to do a job you do it. No matter what. That's show biz. I did it,' she said.

'You show up or if you can't then you say I can't and I'm going to take this season off to heal. But please don't make any of us out to be bullies.'

Reps for Rinna and Kemsley declined to comment when contacted by DailyMail.com.

Lisa was even a no-show at co-star Camille Grammer's wedding last weekend and network execs say they 'have no idea' when they'll get her back to the other cast members.

'I actually feel sorry for her as she is no longer friends with any of the women even Kyle and Teddi - her two best friends from last season.'

'This season will be ratings gold for us, but the trade-off is we'll most likely lose Lisa forever as it doesn't look like she'll come back for the next season.

'Regardless the drama and the addition of Denise Richards will make this one of the best seasons of Real Housewives of Beverly Hills we've ever seen.

'We don't expect Lisa to film with the other women for the remainder of the season and we just hope Lisa will show up and film the reunion as this will be the greatest showdown in Housewives history.'

Both Bravo and Lisa Vanderpump declined to comment when contacted by DailyMail.com.
