Uh-oh! It seems Lisa Vanderpump is no longer Miss Popularity in the 90210.

Following the major blowout with Brandi Glanville and shaky relationship with co-star Kyle Richards, Lisa doesn’t seem to have many old shoulders to lean on these days. The Brit beauty, a current favorite on The Real Housewives of Beverly Hills, opened her new West Hollywood lounge PUMP recently, and though the event was star-studded (fellow RHOBH stars Joyce Giraud and Carlton Gebbia showed up), Kyle and Kim Richards notably absent.

“Kim and Kyle are shutting Lisa out and they want nothing to do with her,” a source close to the stars told RadarOnline.com. “Lisa and Kyle have such bad blood between them and it doesn’t look like anything is going to repair that relationship.”

Kyle was absolutely furious with Lisa in the last season of RHOBH when the opinionated Brit brought up cheating rumors about husband Mauricio Umansky, and we only got a slight apology out of Lisa during the reunion special.

“It was shocking that none of Lisa’s old friends showed up to support her, but that just shows how BAD things are between the ladies that used to be friends,” the source continued. “Lisa thought she would be able to be friends again with Kyle again, but that is never going to happen. And Kim will ALWAYS be loyal to her sister, so she’s not going to be friends with Lisa either.”

Do you really think the Richards sisters are still mad at Lisa? Hit the comments and speculate!
