Holly Madison's Studio 54 Costume Contest

Posted Monday November 1, 2010 2:57 PM GMT

Always up for being the belle of the ball, Holly Madison was spotted at her Halloween contest party at Studio 54 in Las Vegas over the weekend (October 30).

The former “Girls Next Door” hottie looked darling as she posed as Sleeping Beauty for the night while playing host of the swanky soiree held at the MGM Grand Resort.

Keeping her followers up-to-date via Twitter, Madison posted on her wall, “So many amazing costumes at Studio 54! I can't wait to see who wins the contest tonight!”

Turns out, a gal donning nothing but a few green leaves won the contest and was spotted hamming it up with Holly throughout the night.
