They're definitely not pulling a Beyoncé/Jay-Z when it comes to keeping their romance under wraps! Jennifer Aniston and John Mayer followed their Miami lovefest with a concert (his) in Orlando on Tuesday night. John played an hourlong set at the convention center while Jen played the adoring fan, taking pictures of him backstage. At the end of his performance, John went back to steal a kiss from his new lady before playing an encore. Talk about sweet music!
