Busty Heidi Klum adverts banned from Las Vegas

Heidi Klum's bare breasts have been covered up to appease billboard watchdogs in Las Vegas.

Bosses at gadget store Sharper Image hired the German supermodel to pose for their suggestive 2014 Christmas campaign, in which Klum appears to encourage lusty fans to buy quirky items from the company.

However, City of Las Vegas officials took issue with the images of a scantily-clad Klum and told advertising bosses they had to cover her up.

Apparently Klum's cleavage did not meet Clark County code and the adverts were barred from being displayed at various sites, reports TMZ.com.

Sharper Image bosses submitted toned downed pictures, which have now been approved.
