Vanderpump and Glanville were close friends during Glanville's first couple of seasons on The Real Housewives of Beverly Hills, but then, during season four, their friendship took a turn for the worse after Glanville claimed Vanderpump had been manipulating cast members.

During season five, Glanville attempted to reconcile her relationship with Vanderpump, but unfortunately, what was supposed to be playful banter during a cast dinner in Amsterdam resulted in Glanville slapping Vanderpump, which she didn't take kindly to.

In her Bravo blog after the episode aired, Vanderpump explained her decision to cut ties with Glanville for good.

"I never once said the slap was hard," she explained. "The endless accusations last season of lying, deportation, bankruptcy, Ken abusing Yolanda...all that was accumulative and there was not enough there to counter balance it."
