Lisa Vanderpump Is Refusing To Return To 'RHOBH' After 'Leaking' Controversy

Lisa Vanderpump is refusing to return to The Real Housewives of Beverly Hills after a leaking scandal that RadarOnline.com told you about first!

"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.

The restaurant owner's once close pal, RHOBH's Dorit Kemsley, adopted a pup named Lucy from Vanderpump Dog Rescue, the rehabilitation of dogs charity that Lisa runs.

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.
