Blige , Nicole Richie and Victoria Beckham will hold court at the tony Fifth Ave. establishment Bergdorf Goodman.

Musicians who keep a well-styled foot in the fashion world are also at the helm of several of the night’s festivities. Superproducer Pharrell Williams will be on hand for an event at the downtown outpost of his Billionaire Boys Club’s brand, where a (not-so) surprise show will kick off the event in the early evening.
