Heidi Klum is set for a hairy Halloween - she'll be wearing a bizarre monkey costume for the first of two parties in Las Vegas this weekend.
 
Klum will host the TAO Lounge's Halloween bash on Saturday before jetting off to New York for a party at PH-D Rooftop Lounge at the Dream Downtown.
 
For the second bash she'll don a skin-tight flesh and skeleton suit.
