Lisa Vanderpump

The Brandi Glanville-Lisa Vanderpump feud that's been brewing on the current season of The Real Housewives of Beverly Hills heated up on Monday when Glanville appeared on Watch What Happens Live.

Glanville, who's been sore over Vanderpump hiring ex-husband Eddie Cibrian's former mistress Scheana Marie at her restaurant, was asked why she seemed to bite the hand that fed her socially during the late-night show. "Who the f--- fed me?" Glanville retorted, to which Cohen clarified that the caller was referencing Vanderpump.

"No, honestly, she didn't feed me," Glanville said. "She was a good friend. She loaned me a dress one time. That was her big thing. I sat down with Scheana for her multiple times to help her show [Vanderpump Rules]. I said, 'I will do whatever you like,' and then I got tired of it. I think that I fed that b----."
