Ta-ta self-edit-gene-lacking 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 cancelled.

Though 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,” the fat lady sang for the show on Thursday afternoon.

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

It marks the first time in “Housewives” history that an iteration has not moved forward for a second season. The franchise got its start 2006 at the height of ABC network’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 DC 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 a an e-mail exchange with the TV Column in response to our query on 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.)

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

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

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 the time, it the second most watched “Housewives” first season ever, trending behind only “Real Housewives of New Jersey,” with its record 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 it featuring Michaele and Tareq Salahi and all the hoo-ha about their visit to that White House State Dinner which, some say, derailed the show. The other D.C. housewives certainly did not appear any too happy about it in public appearances they made.

But they were not wig-tearing, table-flipping mad. This was a problem.

The housewives of D.C. 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.

Other “Real Housewives” editions also had an advantage over “D.C.” because they were located in or spitting distance from Capitols of Fatuous Media. Those housewives could be seen every night at parties that were being covered by “ET,” and “Extra,” and “Access Hollywood.”

“It’s serious, it’s politics,” Cohen acknowledged at that time. “The level of discourse on this show is different. For people who expect to see table flipping or wig pulling, that was never going to happen on this show.”

Then came “Real Housewives of Beverly Hills.”

With “Real Housewives of Beverly Hills,” Bravo headed back to familiar territory: blond, booby, overstated plastic surgery, major house porn. “Bev Hills” was over-the-top and utterly super-superficial.

It also enjoyed the franchise’s most promising cast ever, having been populated with pre-sold names. In the course of the first season, we saw Camille Grammer getting dumped by hubby Kelsey Grammer on national TV, while Kelsey was off doing “La Cage Aux Folles” on Broadway.

“Beverly Hills” also boasted two Paris Hilton aunts: former child stars Kim and Kyle Richards.

“Real Housewives of Beverly Hills” opened in a big way: 1.5 million tuned in. And the show’s ratings kept climbing until they hit 3 million viewers in the finale -- double the “DC” finale crowd.

Last month Bravo announced “Real Housewives of Beverly Hills” would be back for a second season.

It joins versions set in New York, Atlanta, OC, and New Jersey. “Real Housewives of Miami” has just finished its first season but there is, as yet, no word on its future.
