A newly raven-haired Lady Gaga stepped out last night with Tony Bennett for their special Cheek to Cheek at Lincoln Center. The pop star wore a flowing black kimonolike robe — a style she’s been favoring of late — with a plunging neckline and intricate silver detailing at the waist. She accessorized the look with dangling earrings, a towering bun, and, of course, octogenarian arm-candy.
