The TV Column: ‘Real Housewives of D.C.’ won’t be back for second season

Ta-ta, royalty-canoodling Cat Ommanney!

Bye-bye, modeling-agency matron Lynda Erkiletian!

So long, mom-of-five/Arthur Godfrey granddaughter Mary Amons!

See you ’round, real-estate agent Stacie Turner!

And we think we’ll miss you most of all, Michaele Salahi!

“The Real Housewives of D.C.” has been canceled.

Cat confidently told The Post in late February that the deafening silence since the show’s October 2010 finale “has made people think there won’t be one, but I’m quite confident that there will be a second season.”

But the fat lady sang for the show Thursday afternoon.

Bethesda-based Half Yard Productions contacted the cast members to let them know that Washington’s contribution to Bravo’s hot docu-soap franchise would not be picked up for a second season.

This marks the first time in “Housewives” history that an iteration has not moved forward for a second season. The franchise got its start in 2006 at the height of ABC’s “Desperate Housewives” mania.

“We had an amazing season and we told stories that were unique to any other in the franchise. I wish all our D.C. wives the best and hope to work with them again in another capacity,” Andy Cohen, Bravo’s executive vice president of original programming and development, said in an e-mail exchange with The TV Column, in response to our query Thursday.

“In fact, Cat is booked on our April 28th ‘Watch What Happens Live Royal Wedding Spectacular,’ ” added Cohen — ever the showman.

(Cat is, of course, the most qualified person in this country to cover the storybook wedding of Britain’s Prince William and Kate Middleton, having claimed to have made out with the wedding’s best man. That would be Harry — William’s brother.)

Cohen says he’s already working on new projects with Half Yard.

“Real Housewives” series set in other cities have typically rushed a second season onto Bravo’s lineup within a year of the first season. The cable network has already announced a second season of “Real Housewives of Beverly Hills,” which debuted after the wrap-up of the “D.C.” version and finished its first run in January.

But Bravo had remained tight-lipped regarding a second season of the Washington show. And, there were never any signs around town of shooting new episodes.

So what killed “D.C.”?

“Beverly Hills.”

“Real Housewives of D.C.” had performed respectably in its first season, averaging about 1.4 million viewers. At that time, it was trending behind only “Real Housewives of New Jersey,” which had a first-season audience of 2.6 million.

And the first season of “Real Housewives of D.C.” did not lack for press buzz, what with its featuring Michaele and Tareq Salahi and all the hoo-ha about their “gate-crashing” visit to that White House state dinner that, some say, derailed the show. The other D.C. housewives certainly did not appear any too happy about it in the public appearances they made.

But the housewives of D.C. were not wig-tearing, table-flipping mad. This was a problem.

They were, quite simply, too dignified. Too Washington.

“It’s less noisy,” Cohen acknowledged of the Washington version, back in October when being interviewed by The TV Column.
