Lisa Vanderpump is currently having issues with a number of her Real Housewives of Beverly Hills co-stars. But is there now bad blood between Lisa and former Real Housewives of New York star Bethenny Frankel as well?

Nothing seems to have happened between Lisa and Bethenny directly to cause a feud, but Lisa is apparently miffed about things that have been said about her on Bethenny's talk show. 

The drama started when a Twitter follower tweeted at Bethenny and Lisa to say that she is glad to see Lisa's restaurant, SUR, serving Bethenny's cocktails. "I'm loving that you sell #SkinnyGirl drinks at #Sur Good job supporting @Bethenny Woohoo!" the fan tweets on December 19.

"That is very nice!" Bethenny responds. However, Lisa's response isn't quite so upbeat.

"Ha, yes  even though she keeps trashing me!" Lisa tweets about Bethenny. "I don't pay attention... never mind and good morning."

But what exactly is Lisa talking about? Well, Bethenny has had several guests on her show lately  including Brandi Glanville and Kim Richards — who have said negative things about Lisa. So we're guessing Lisa feels Bethenny should have defended her.

Do you think Lisa is right to criticize Bethenny for what her guests have said?
