Heidi Klum's breasts are apparently too hot to be displayed in Las Vegas.

Accordignt to TMZ.com, Sharper Image new ad campaign featured a scantily dressed Klum, 41, however, since the supermodel's cleavage did not meet Clark County code, the ads were barred from being displayed at McCarran Airport.

The problem was "the showing of the female breast with less than a fully opaque covering or any portion thereof below the nipple," meaning, the display of underboob.

Sharper Image has now submitted a toned downed version of the images, which have been approved, and will soon be displayed for all to see.
