Nicole Richie celebrated her upcoming wedding to Joel Madden with a bachelorette party in Cabo San Lucas.
Richie and pals including Christina Aguilera, Samantha Ronson and hairstylist Andy LeCompte, stayed in two oceanfront villas at Las Ventanas Resort.
At night, they ventured downtown for dinner at Mi Casa restaurant and dancing at Mandala Club where they wore masks to remain incognito.
As favors, guests received t-shirts that read “Nicole’s Bachelorette 9/17/10” which Christina Aguilera wore home.
