Heidi Klum and Paulina Porizkova Are Coming to Desperate Housewives!

The supermodels will appear as themselves in an upcoming episode slated to air in March

How many hot mommas can one show hold?

Apparently, two more when it comes to Desperate Housewives.

Sources tell me exclusively that supermodels and reality-TV staples Heidi Klum and Paulina Porizkova have just signed deals today to guest star on the hit ABC series. A rep for ABC confirms this new to us.

So who are Heidi and Paulina playing?

According to sources, they'll be playing themselves in an episode tentatively slated to air in March. And sorry, Desperate dudes, but it'll be solely a female affair.

In the episode Gaby (Eva Longoria Parker), who is a former model, and Angie (Drea de Mateo) run into the Project Runway host and former America's Next Top Model judge in New York City. The storyline will take place in NYC but the episode will be shot here in Los Angeles.

I'm told Heidi and Paulina's deals just closed today, so the ink is still drying. This is arguably Desperate Housewives' splashiest/sexiest guest-star casting yet, though there have been some seriously fine actors to come through Wisteria Lane, including Alfre Woodard, Nathan Fillion, Neal McDonough, Dougray Scott and John Slattery.
