Perhaps now they are just friends that like to hang out together, but after two failed attempts at romance are Jennifer Aniston and John Mayer going to rekindle? Aniston who is watched like a hawk by the media, was spotted last month going out with ‘Cougar Town’ star Josh Hopkins, and perhaps also spent time recently with Lindsay Lohan’s ex, restaurant owner Harry Morton. But Jen is now in Atlanta shooting her next movie “Wanderlust”, and John was performing Wednesday night at Aaron’s Amphitheatre in nearby Lakewood, Georgia. So Jen quietly supposedly slipped backstage in “workout clothes” and a baseball cap to watch Mayer perform, according a Radar source. After the concert the duo, along with a group of people connected to Mayer’s tour, headed over to a Ritz-Carlton, where Aniston is reportedly staying during the ‘Wanderlust’ shoot. Radar reports that the famously outspoken musician then rented a suite for an impromptu one-night-only private party. Mayer & Co. then traveled to Florida the following day for his next gig in Tampa, FL This may not be the first time Aniston, 41, and Mayer, 32, who ended their on-off yearlong relationship in 2008, have gotten together of late. Mayer took the HuffingtonPost to task last month for reporting that he and Aniston were dating and had been seen together at another concert at the Hollywood Bowl, but he didn’t deny that they had been together.
