Is Former Real Housewives Star Kelly Bensimon Dating Madonna's Ex?!

Sometimes all it takes is a simple stroll to get tongues wagging.
And if rumors are to be believed, former Real Housewives of New York City star Kelly Bensimon and one of Madonna's ex-boy toys are doing way more than just walking around the Big Apple.
The two were reportedly spotted on the streets of the East Village over the weekend, with one website quoting a source saying "they started out working on a project together, but have since gotten very close...we all know that they are together."
But which of the Material Girl's guys are we talking about here?

That would be Carlos Leon, who shares a daughter, Lourdes, with the pop icon.
However, a rep for Bensimon refutes the Huffington Post story, telling E! News that the onetime reality TV star and Leon are friends, but they are not dating.
Don't worry, Carlos. There are plenty of other housewives fish in the sea.
