Katherine Heigl's Nobu Birthday Festivities

"Grey's Anatomy" Emmy-winner Katherine Heigl celebrated her 29th birthday this past Saturday with friends and family at the Malibu outpost of Nobu. A spy told Huffington Post that Heigl, dressed down in a tweed blazer and bun, sat between costar and best friend T.R. Knight (hard to recognize with a new buzz cut) and her fiance Josh Kelley at a round table of about eight people. One older woman appeared to be Heigl's mom.

'When the cake came, the whole restaurant sang "Happy Birthday dear Katie" to her,' said the spy. The cake even featured some sparklers on it. But, no presents for Heigl, who was treated just like anyone else by the waitstaff, who resisted fawning.

They also resisted fawning over Hollywood lawyer Bert Fields, who sat one table over.
