Actress Rebecca Mader hosted a LOST finale smash at LAVO over the weekend. Though you may know her as anthropologist Charlotte Lewis, friends and partygoers got to learn a bit about her wild side. Mader danced the night away with DJ FIVE after a spread of appetizers that included chic hors d’oeuvres such as Kobe meatballs and Oreo Zeppole. LAVO also presented Rebecca Mader with that fantastic cake.

Mader also made an appearance at the Carrera Escape at TAO Beach, which was hosted by Wilmer Valderrama. Carrera Escape is meant to be an urban retreat for celebrities, sponsored by the eyewear company.
