A source close to Jennifer Aniston says that the actress has fallen hard for new boyfriend John Mayer. The couple have only been dating a few weeks, but the source says Aniston is already “so happy” with Mayer.

“She’s just so happy and giggly. It is completely out of character,” says the insider.

 

While Aniston is happy, Mayer’s ex-girlfriend Jessica Simpson is said to be upset over the romance. Sources allege the singer went on a “drinking binge” when she heard that Mayer and Aniston were dating.
