'Real Housewives' stars Lisa Rinna, Harry Hamlin and Nicollette Sheridan in heated Twitter feud

Real Housewives of Beverly Hills” stars Lisa Rinna and Harry Hamlin are doubling down on their claim that co-star Nicollette Sheridan cheated on Hamlin with pop star Michael Bolton while they were still married.

The allegations stem from the latest episode of the Bravo reality series where Rinna, who has been married to Hamlin since 1997, alleged that Sheridan went to a Bolton concert and left with him, sparking their divorce and leaving the way clear for Rinna to pick up the pieces, People reports.

Days after the allegations debuted, Sheridan took to Twitter to decry the rumors as “fake news.”

“Harry and I ended our marriage nose to nose in Canada… Michael was a long time friend that was invited to our wedding… Happy Harry found happiness with housewife @lisarinna,” she wrote.

Adding fuel to the fire, Hamlin chose to chime in at this point, taking to Twitter to slam his ex-wife and reiterate the cheating claims.

“Re Fake News! What’s it called when your wife of one year suddenly goes to bed with a pop singer? …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!” he wrote.

Rinna replied soon after, twisting the knife by calling Sheridan “the gift that keeps on giving.”

ET Canada reports that Rinna penned a lengthier retort on her Instagram Story that has since been deleted that read: “My bad, I’m sorry, Nicollette. I forgot to thank you also. Thank you for f---ing Michael Bolton and cheating on Harry while married. I thought I’d take the high road and not tweet this… NAH.”

In what appears to be a response to Hamlin’s tweet, Sheridan fired back by threatening to share truths that he might not want made public.

“Do you really want the truth shared?” she tweeted on Saturday. “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.@HarryRHamlin @lisarinna.”
