Dorinda Medley's Boyfriend Throws Ramona Singer Out Of A Party Get details on the reality stars' big blowout.

Real Housewives of New York drama occurred off-screen this week when Ramona Singer was booted from a party for defending an intoxicated guest.

The 59-year-old went out for a sushi dinner with costars LuAnn de Lesseps and Sonja Morgan before the gang made their way to a bash hosted by Dorinda Medley‘s beau John Mahdessian.

But things took a turn when “an uninvited drunk” began “harassing” the ladies during the party, Page Six reports.

According to onlookers, Mahdessian quickly stepped in to help, but Singer “oddly asked the drunk to stay, ensuing in a screaming match.”

As a result, Mahdessian “had them both removed,” an insider told the publication.

Party guests reportedly applauded the Madame Paulette –– a couture dry cleaning and restoration service –– business owner, but Singer was also spotted having the last laugh out on the street with her new companion.

As Radar previously reported, it took a long time for newcomer Medley to get her cast mates to accept Mahdessian, whom the ‘Wives have accused of being overly flirtatious.

Will Dorinda have to apologize to Ramona? Let us know what you think in the comments below!
