Bill de Blasio’s inaugural committee is star-studded.

The mayor-elect announced Saturday that Harry Belafonte, Sarah Jessica Parker, Steve Buscemi, Susan Sarandon, Rosie Perez and Russell Simmons are among those helping organize the festivities surrounding his inauguration.

Gabrielle Fialkoff, the chief operating officer of a jewelry firm, was named chair. She served as finance chair for de Blasio’s runs for public advocate and mayor.

More than 50 supporters will serve on the committee that will plan celebrations in all five of the city’s boroughs.

He takes office Jan. 1 and is expected to name the first members of his administration within the next week.
