Jennifer Aniston stepped off the NYC set of The Baster yesterday. Despite the fact that she'll be in town for Monday's big Costume Institute Gala, don't expect to see her next to Anna Wintour. Jen was apparently in talks to attend, but decided not to go because it was too big a time commitment. Another thing Jen won't be doing is adopting — despite recent stories that she was getting advice on the subject from Brad Pitt, her rep quickly shot down those rumors. For now, at least, the only little one in Jen's life is her adorable young costar.
