EXCLUSIVE: Lisa Vanderpump & Eileen Davidson STILL At War Over Dog Joke

Real Housewives of Beverly Hills is wrapped for the season, but RadarOnline.com has exclusively learned that the war between rivals Lisa Vanderpump and Eileen Davidson has just begun to heat up!

After the 56-year-old blonde soap star slammed Vanderpump's passion for pets last week, a source close to the situation said, "Eileen has still not apologized." As RadarOnline.com reported, Davidson made a sarcastic joke about murdering dogs on her Bravo blog, when she explained why she didn't attend an animal rights event hosted by Vanderpump.

According to the insider, however, "Eileen told the other housewives that all she really meant by the comment was that Lisa should perhaps use her social platform to help actual humans instead of animals."

Obviously, that did not sit well with the 55-year-old veteran RHOBH star, who, in addition to being the face of Stop Yulin Forever, owns a dog successful dog accessory company, Vanderpump Pets.

The doggie drama might seen much ado about nothing, but as RadarOnline.com previously reported, tensions between Davidson and Vanderpump go back to last year, when the duo clashed on a red carpet.

At the time, an eyewitness said, "Eileen was incredibly rude and gave Lisa a look like she didn't even know who she was."

And – as fans of the hit Bravo show know – the two beauties have been at odds since the beginning, when Davidson joined the cast with a record newcomer salary of $750,000!

But the war may end even before it makes it to air, as the source told RadarOnline.com, "Lisa does not want to work with her again next season. She wants her gone!"
