John Mayer and Jennifer Aniston broke up for the second time a few weeks ago! The couple had gotten together around the time of Jen's Marley & Me premiere, broken up around the time He's Just Not That Into You hit theaters, and got back together again in time for the Academy Awards. They're apart, again!!!! Is it for good this time. Jennifer just can't seem to get in the nitch of things when it comes to relationships ever since her divorce from Brad Pitt.
