Unfortunately for Barney, Glanville immediately took offense, and called her out in a tweet of her own.

After being asked about Glanville's claims of having quit her full-time gig with Bravo -- even though they offered her a substantial amount to return, Barney said, “We have the same production company and her numbers do not match up. I know who she’s negotiating with. Let’s just put that on the table right now … I’m going to offer you $500,000 to work four months out of the year and you decide, ‘No. I’m going to try to find another job.’ No. Sorry. It doesn’t work that way.”
