If there's one thing we can say for Andy Cohen, he knows how to mix it up on Bravo's "Watch What Happens Live." On Thursday's (April 28) episode, not only did he have former "Real Housewives of DC" cast member, Cat Ommanney, on after the network unceremoniously canceled her series, but he threw in divorced royal, "The Real Housewives of New York's" LuAnn De Lesseps.

It didn't take long before Cat began showing her dislike for LuAnn when Andy played a game in which The Countess judged the Brit (who made tabloid headlines after making out with Prince Harry) on her royal manners.

Not only that, but Cat took to Twitter and Facebook to make sure her feelings on The Countess were clear.

"Sorry everyone, I just wanted to clarify," she writes. "I REALLY DIDN'T ENJOY at all, being on #WWHL with @countessluann infact thought she was #notmybagatall #condescending and hope we never cross paths again #ever."

So, what did LuAnn have to say in response? "Well that was fun....," she tweets.

The best part is that Cat really unloads on LuAnn during the untelevised after show -- God bless alcohol.

Watch as Cat tells LuAnn where she can put her lady hat:
