Star comedians Dana Carvey and Whitney Cummings made guests chuckle during the "Roast Rosey" portion of the evening entertainment.

Guests were greeted with a gift of sway: sparkling tiaras and orange floral lapel pins.

Throughout the evening atmosphere performers costumed in hues of orange and white, accented with LED and sparkling diamanté posed for photos and acted as impromptu dance partners.

A custom-built photo-opportunity featured an orange carpeted snow globe set against an alpine backdrop. As guests stepped into the light, billowing snow descended upon them, a highly unusual moment for Las Vegas.

A custom tangerine carpet emblazoned with the Birthday Bash logo led guests along the pool deck. Snow flurries drifted above performers dancing atop the water floating inside crystal orbs.

An orange fondant covered Chanel handbag cake overflowing with bubbles from a bottle of Dom Perignon displayed Rosey's love of both champagne and Chanel couture.

A sway pole performer set amongst twinkling birch trees beckoned guests down the pathway.

Servers dressed in gloves and winter ear warmers served Creamsicle Cocktails and Champagne Punch.
