As the summer season kicks in, Jennifer Aniston was spotted shopping at ‘Fred Leighton Rare Collectible Jewels’ on Madison Avenue in New York City. She was sporting a tube top and looked stunning as always. Later, she headed to the Metropolitan Museum of Art. While Katie Holmes might be acing the pegged-jeans look, Jennifer was seen rocking the baggy-jeans style. Meanwhile, John Mayer, Jennifer’s ex-boyfriend, visited his favorite Japanese spot Nobu Next Door on Thursday.
