Scheana Shay and Brandi Glanville appeared to be on the verge of putting their troubled relationship in the past just days ago, but on Monday, during an appearance on "Watch What Happens Live," their potential reconciliation was shot down.

As fans may recall, the former "Real Housewives of Beverly Hills" star appeared on the show last week and revealed to host Andy Cohen that she was actually a fan of Shay's role on "Vanderpump Rules" season five. "Honestly, Scheana's the only girl that I like this season," Glanville said at the time, adding that Shay was the "normal" one -- and the "voice of reason."

After hearing what Glanville had said on the show, Scheana Shay was seen in the Bravo clubhouse, where she revealed that her jaw dropped upon hearing her former nemesis' comment.

"I was like, 'Rewind. Wait, she did say it.' Then I went to tweet her and I'm like, 'I'm still blocked,'" she revealed.

Scheana Shay was involved in an affair with Brandi Glanville's husband in 2006

Prior to her marriage and divorce from Mike Shay, Scheana Shay was involved in a relationship with Eddie Cibrian. As she revealed to Access Hollywood in 2009, their romance began in 2006, years before he was caught cheating on Glanville, whom he wed in 2000, with country singer LeAnn Rimes.

As fans may recall, Shay and Glanville's issues have been addressed on both "The Real Housewives of Beverly Hills" and "Vanderpump Rules" and in 2013, when the spin-off series began, it kicked off with a meeting between the two women.

On episode one, which aired as a crossover episodes, Shay and Glanville sat down at SUR Restaurant to discuss what happened between Shay and Glanville's now-ex-husband years ago. Although there was not much resolve between them, the episode made for quiet the dramatic lead-in to "Vanderpump Rules," and the series has remained a hit for Bravo in the years since.
