Alessandra Ambrosio looked sensational in a Jessica Rabbit outfit from the 1988 film Who Framed Roger Rabbit?
The model wore a strapless red dress with a sweetheart neckline and matching red pumps.
The Victoria's Secret vet added a long red wig and purple satin gloves.
Also with her was her fiance Jamie Mazur.
His outfit didn't quite impress as much. He had on a motorcycle jacket and bunny ears, making it unclear what he was trying to be. But he may have been rushed putting their two kids to sleep before they hit the bash.
On Friday night Cindy Crawford and husband Rande Gerber dressed up as punk rock stars. Also there were their model kids Presley and Kaia, who kept with the theme
Husband Gerber dyed his hair purple and wore red eye makeup.
He too was punked out, looking a bit like Justin Theroux on an average day.
He added a black T with a leather motorcycle jacket and heavy boots.
Also there was Emmanuelle Chriqui as a rocker chick and Jenna Dewan Tatum as a sexy unicorn
Lisa Rinna was Cher and Harry Hamlin was Sonny for this inspired partnership
