And most of them we’ve seen before. . . . Time magazine announced Thursday it will be bringing Steven Spielberg, for the fourth time since 2009. Also, Julia Louis-Dreyfus, who also attended in ’09, with husband Brad Hall. New this year: Olympic gymnastic champion Gabby Douglas. And Bollywood star Aamir Khan. (From the world of non-celebrity: Movie producer and Obama supporter Jeffrey Katzenberg; Obama advisers Dan Pfeiffer and David Plouffe; Israeli Ambassador Michael Oren).
