As the summer season approaches, Jennifer Aniston flaunts a tube top while shopping at ‘Fred Leighton Rare Collectible Jewels’ on Madison Avenue in New York City. Later, she heads to the Metropolitan Museum of Art, looking stunning as always. On the other hand, Katie Holmes seems to have perfected the pegged-jeans look, but Jen prefers to rock the baggy-jeans style. Meanwhile, her ex-boyfriend John Mayer was spotted enjoying his Japanese cuisine at Nobu Next Door on Thursday.
