Video: Rhapsody in Zoo

As photo shoots go, it was somewhat atypical. Sure, the ingenue wore fur, and attendants were suitably admiring. But the subject was shockingly young, and the photographers' dizzying demands produced a foot-in-mouth—er, -bowl—moment or two. Before long, the poor thing was worn out and needed some beauty sleep. Knut, a polar-bear cub born at the Berlin Zoo, amiably bared all for Annie Leibovitz and Vanity Fair's Green Issue cover, which he shares with a not quite as hirsute, though suitably cute, Leo DiCaprio. And a star is born.
