The latest Real Housewives of Beverly Hills feud began when Glanville announced on her Podcast that Vanderpump and hubby Ken Todd had once lived in the Valley and even filed for bankruptcy before appearing on the hit Bravo show.
After it made headlines, both Vanderpump and Todd fiercely defended the claim — so Glanville passed the buck to co-star Kyle Richards, claiming she told her the gossip on the successful British couple.
"Kyle Richards told me, I looked it up and on this site where you pay $9.99 it said yes, they lived off Mulholland drive in Calabasas," Glanville told E! News last week.
But Vanderpump is sick of Glanville talking about it, and let her know it Monday morning on Twitter.
Meanwhile, Richards is angry about being brought into the feud between the former BFFs.
"Finally, just when Lisa and Kyle were in a good place with their friendship, and Brandi starts running her mouth, again," a source previously told Radar.
"Kyle made the mistake of trusting Brandi with information in the past, and now, that has bitten her in the ass. Brandi point blank asked if there were any skeletons in Lisa’s closet….Kyle absolutely wasn’t the one to tell Brandi about these ridiculous rumors about financial problems with Lisa and Ken."
No telling when this drama will cool, but sources tell Radar that if Glanville doesn't back down soon and take full responsibility for spreading a lie, Vanderpump will take legal action.
