As the summer season approaches, Jennifer Aniston is spotted wearing a tube top while shopping at Fred Leighton Rare Collectible Jewels on Madison Avenue in New York City. She then heads to the Metropolitan Museum of Art for some leisure time. Although Katie Holmes may be known for her pegged-jeans look, Jen seems to be embracing the baggy-jeans style. Meanwhile, ex-boyfriend John Mayer was seen having a meal at his favorite Japanese hotspot, Nobu Next Door, on Thursday.
