"It's all-out war on the Real Housewives of Beverly Hills and we cannot get Lisa to film with the entire cast," a source told the Daily Mail.
"She's said enough of the b****iness and called time on filming with the other women."
According to the Daily Mail insider, the restaurateur is telling Bravo producers she wants nothing to do with her co-stars after they accused her of leaking stories to the press.
Actually, as previously reported, Vanderpump was specifically alleged to have leaked to RadarOnline.com, a source said.
But RadarOnline.com boss Dylan Howard has staunchly denied that Vanderpump did so, saying, "Lisa has never been an anonymous source to the site — although I for one wish that she was! She’d be as rich with information as she is rich is real-life!"
Still, Vanderpump has not been with her co-stars lately, snubbing Camille Grammer's wedding last weekend in Hawaii.
RadarOnline.com exclusively learned that a dog has caused the tension.
As RadarOnline.com noted, Dorit, 42, "abandoned" the dog in a move that left Lisa, 58, fuming.
Now, the cast is privately accusing the larger-than-life TV star of being the mole for oodles of negative stories to RadarOnline.com, the source noted.

That doesn't sit well with the RHOBH queen, and the source told the Daily Mail, "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."
