Sin City is cleaning up its act! A few weeks after Sharper Image debuted its holiday campaign featuring a scantily clad Heidi Klum, the ads were banned from McCarren International Airport in Las Vegas. Apparently, the black-and-white shots of the supermodel violate Clark County's stance against "the showing of the female breast with less than a fully opaque covering or any portion thereof below the nipple." (This sounds like a bit of a technicality to us, but what do we know?) The "Gift Right" campaign's images show the America's Got Talent judge lounging casually in various states of undress. From a slinky black dress (basically the unofficial uniform of women in Las Vegas) to worn-in jeans to nothing at all, her looks definitely capture your attention… which, we're pretty sure, is precisely what Sharper Image was intending. Next to the pictures are suggestive questions with surprising answers. "What turns Heidi Klum on?" one banner asks: The answer is the Sharper Image charge tower. Another wants to know, "What keeps Heidi Klum busy in the shower?" Give up? It's the company's shower speaker, obviously. A rep for the airport confirmed the ban to The Insider With Yahoo, but noted that they use an outside agency for these approvals, and it was them who made the decision about the Sharper Image ads.
