Nicole Richie and Joel Madden hit the red carpet at the Sony Cierge and The Richie-Madden Children’s Foundation event, held at MyHouse in Los Angeles.  The UNICEF cocktail party was a private charity function.

The couple are expecting their second child.  These latest photos showcase Nicole’s obvious baby bump.  Daughter Harlow turned one-year-old in January.

Also on hand for the event was Benji Madden.  The brothers are co-founders and performers in the band Good Charlotte.
