As summer draws near, Jennifer Aniston was spotted shopping at ‘Fred Leighton Rare Collectible Jewels’ on Madison Avenue in New York City. She was looking fabulous in a tube top and then later headed to the Metropolitan Museum of Art. Jen has her own unique style, opting for baggy jeans over the popular pegged-jeans look that Katie Holmes has been sporting. In other news, John Mayer was seen dining at Nobu Next Door and seemed to be enjoying his Japanese cuisine.
