Everyone, including Kate Hudson, Fergie and Adam Lambert got a turn at the mike during the party. While Josh Duhamel, Cindy Crawford and her husband Rande Gerber hung out with the gang and looked to be having some fun themselves.
Fergie, who just turned 36 on Sunday, still seemed to be in the partying mode. Kate Hudson seemed to be doing some extra mugging for the camera.
