Have Jennifer Aniston and John Mayer decided to rekindle their summer romance?

According to Us Weekly, that's a yes! The mag states that the "Body is a Wonderland" singer and his "Friend" went to a concert in Boston together on Friday -- then jetted to the Big Apple for a weekend getaway. "It was a very public date," a source reveals.

Aniston, 39, and Mayer, 30, called it quits in August. The couple had been inseparable since being spotted kissing poolside in April.
