ICYMI: Sheridan was none too pleased when, on "RHOBH" earlier this season, Rinna accused Nicollette of cheating on Harry with Michael Bolton when they were married in the '90s.
Last night, a caller asked how Rinna felt "about the accusations by Nicollette Sheridan against your marriage." Sheridan, it should be noted, never actually said anything about Hamlin's relationship with Rinna, simply calling the Michael Bolton narrative "fake news."
Rinna's response: a sip from her rosé and the middle finger. "That's how."
Host Andy Cohen noted that Sheridan started following him on Twitter "the other day," something which didn't surprise Rinna in the least. "I bet she did," Lisa shot back, "She probably needs a job. Was that shady?"
Seriously though, how great would Sheridan be as an addition to the show? In addition to her history with the Rinna-Hamlin family, she was also previously married to Aaron Phypers, who's currently married to Denise Richards. The drama!
In an episode that aired back in February, Rinna said, "The story is, [Sheridan] went to a Michael Bolton concert at the Hollywood Bowl ... and left with Michael Bolton!" She claimed Harry was "in Canada" when it happened.
"FAKE NEWS! Harry and I ended our marriage nose to nose in Canada," Sheridan tweeted after a clip from the episode went viral. "Michael was a long time friend that was invited to our wedding...Happy Harry found happiness with housewife @lisarinna."
"Re Fake News! What's it called when your wife of one year suddenly goes to bed with a pop singer?" Hamlin tweeted in response. "Two weeks after your mother dies?? I did a lotta stuff with my wife 'nose to nose' but ending our marriage was not one of them!"
Sheridan hit back, saying, "Do you really want the truth shared? I appreciate that you want to support your housewife's FAKE NEWS narrative, but the end of our marriage had nothing to do with anyone other than us. Sad you still can't own your part."
Rinna retweeted her response, adding, "Sweetie @IamNicollette You're the gift that keeps on giving!" She also shared a since-deleted post on Instagram thanking Sheridan for "f--king Michael Bolton and cheating on Harry while married."
