Jennifer Aniston doesn't seem to let her fresh breakup from John Mayer slow her down. Aniston was spotting shopping at Fred Leighton Rare Collectible Jewels (classy) on Madison Avenue, August 20, 2008. Did she buy herself a new best friend? Then, she headed for the Metropolitan Museum of Art. Jen was wearing a pair of loose-fitting men's style jeans (which are fast becoming the trend of late summer). [CFP]
