Now that Lisa Vanderpump has left the building, Brandi Glanville has unleashed a savage attack on Orange County housewife, Tamra Judge - calling her a "c*nt" on Twitter.

Over the past two episodes of Real Housewives of Orange County, viewers have seen the ladies gossipping about a rumor started by friend of the show, Vicki Gunvalson about Kelly Dodd having a "sex train" with eight men.

Kelly denies the allegations.

Brandi was not impressed by the ladies helping to spread the awful rumor - especially Tamra.

"I have much to say on the toxic trick that is Tamara but I'm going to enjoy my holiday wknd first & address it on my next you tube episode," Brandi tweeted Saturday. "C*NT f*cking wait!"

Tamra caught wind of the tweet and responded:

"Looks like someone needs a little attention," Tamra responded. "Who knew saying 'Kelly is the new Brandi' she'd lose her sh*t. It's not like I called her a hypothetical as*hole. #calmdowngirl #attorneywatching #heresyourattention #takeitallin."

Oh dear, cross-franchise beef!
