Leighton Meester 'Pushed Off' Asian Gossip Girl Character Nan Zhang?

'Gossip Girl' bad girl Leighton Meester reportedly kicked out costar Nan Zhang, who played her sidekick Kati Farkas. An insider dished, 'she was pushed off the show, Leighton didn't like her, and she went.' The show's rep remarked, 'I think [Zhang] may have had another opportunity come up, but I know she was big into school [Brown University].'

Leighton donned a plunging tank top to celebrate her 22nd birthday Tuesday at Hollywood’s Egyptian Theatre for the premiere of  'Remember the Daze'.
