Chris Pine, Zachary Quinto and Benedict Cumberbatch celebrated the premiere of “Star Trek Into Darkness” at a private after-party at new Meatpacking hot-spot restaurant Manon following the VIP screening at Lincoln Center Thursday night. Newly single Pine, who recently split with model girlfriend Dominique Piek, was sporting a beard and “seemed subdued as he hung out with a few friends at a private table until around midnight when he left alone,” a witness reports.
