Olivia Culpo -- Too Hot For Emmys Red Carpet … Nearly Faints

Olivia Culpo was so hot on the Emmy Awards red carpet she nearly passed out.

Nick Jonas' ex was doing pre-Emmys coverage with Giuliana Rancic, and when the cameras cut back the Miss USA 2012 was down on the ground. Medics tended to her shortly after.

Culpo blamed it on the weather, saying “OMG it is SO HOT out here. Literally just almost passed out.” Temperatures nearly reached 100 degrees Sunday in downtown LA.

Bad day to be wearing evening gowns and tuxes.
