Yet another Real Housewives feud, y’all, except this one is in the family. Sort of. Real Housewives of Beverly Hills star Lisa Rinna and her husband, Harry Hamlin, recently clapped back at his ex-wife, Nicollette Sheridan, on social media after she responded to Lisa’s claims that she cheated on Harry with singer Michael Bolton during their marriage.

The drama started on February 22, when the Dynasty star, 55, retweeted a clip from RHOBH where Lisa, 55, alleged that Nicollette hooked up with the 65-year-old crooner when she was married to Harry, 67.

“FAKE NEWS,” she wrote in her retweet. “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.”

Believe it or not, the Mad Men alum came through with a response to his ex: “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 [sic] stuff with my wife ‘nose to nose’ but ending our marriage was not one of them!”

Lisa chimed in with her own witty comment as she retweeted his response. “Sweetie @IamNicollette You’re the gift that keeps on giving,” she added, even tagging the actress so she’d see Harry’s response. Yikes.

The RHOBH star even mentioned it on her Instagram Stories, according to Us Weekly. “My bad, I’m sorry @IamNicollette I forgot to thank you also,” she wrote. “Thank you for f—king Michael Bolton and cheating on Harry while married. I thought I’d take the high road and not tweet this … NAH.”

Michael is the only one involved in the rumors who hasn’t commented on the war of words at this point, but it would be interesting if he jumped into the social media fold and gave his two cents as well. Either way, expect Lisa Rinna to keep speaking her mind.
