Although they've kept their relationship quiet, In Touch has learned that John Mayer is crazy about Jennifer Aniston. He flew to Miami on April 23 and checked into the Four Seasons hotel, but insiders say that he spent virtually no time there during his visit — opting instead to hang out in the $3,000-a-night presidential suite at the Mandarin Oriental, where Jen has been staying while shooting the movie Marley & Me. And the two were inseparable over the long weekend. When asked how he was doing, after spending four days with his new love, John smiled. "My weekend was good," he told In Touch exclusively.
