Kate Walsh and Nicole Richie arrive at the 2011 UNICEF Ball held at the Beverly Wilshire Hotel on Thursday (December 8) in Beverly Hills, Calif.

The 44-year-old Private Practice star brought her boyfriend, writer Chris Case, as her date and also met up with legendary music producer Quincy Jones inside the bash.

Nicole, who’s Quincy‘s goddaughter, stepped out in an Osman dress.

She finished off her look with jewelry by Neil Lane and her House of Harlow 1960 line, HOH 1960‘s “Nora” shoes, and HOH 1960‘s “Orlina” clutch.
