There weren’t any catfights at last night’s (October 23) joint premiere party for The Real Housewives of Beverly Hills Season 4 and Vanderpump Rules Season 2 — but that doesn’t mean there wasn’t drama. A guest at the L.A. bash exclusively tells Wetpaint Entertainment that relations between former besties Lisa Vanderpump and Brandi Glanville are so tense, they spent the evening on opposite sides of the room.

“They completely avoided each other,” the guest explains. “Brandi hung out at one end of the party with Kim and Kyle Richards, while Lisa stayed on the other side for the most part.”

“Their friendship,” the guest adds, “does not seem to be in a good place.”

Other than that, we’re told it was a tame evening — by Housewife standards at least. “The cast had been warned there’d be a lot of press around, so everyone was on their best behavior,” the guest notes.

“The food was really good and Tom [Sandoval] from Vanderpump Rules was pouring shots from behind the bar.”

We’re glad a good time was (mostly) had by all. Now, bring on the drama!

The Real Housewives of Beverly Hills and Vanderpump Rules kick off their new seasons on Monday, November 4, at 8 p.m. and 9 p.m. ET, respectively,  on Bravo.
