"Starbox" Hides Secret Celebrity In Bryant Park is putting a celebrity in a box and plopping them down in Bryant Park.

Beginning July 23, the "starbox" will be inhabited by a secret celebrity, and visitors are invited to come take a peek at who's inside.

Artistic Director Mary Birnbaum said, "We invite lots of speculation about who the celebrity will be. It's someone probably everybody knows and someone that probably everyone likes."

Birnbaum would not comment on exactly how big a star the box dweller will be.

Before guests enter the box, they'll be required to sign a non-disclosure release.
