Good Charlotte star Joel Madden and his girlfriend Nicole Richie will flip the switch on Los Angeles shopping mecca Rodeo Drive's Christmas lights.
The couple will be the special guests at the Unicef + City of Beverly Hills 2008 Snowflake Lighting ceremony on 22 November (08), which will illuminate the 20 Baccarat chandeliers that light up the night and mark the start of the holiday season in Beverly Hills.
Madden was named a UNICEF Goodwill Ambassador in July (08).
