It appears that "Friends" star Jennifer Aniston is very unlucky when it comes to love. She has been dumped by her latest boyfriend, rock singer John Mayer.

According to Mirror.co.uk, Jennifer and John decided to spend some time apart, but then decided to make the break official.

Which means Jennifer has been unable to find love, since her divorce from Brad Pitt four years ago.

Marriage, for Jennifer anyway, seems to be out of her grasp right now. "There's been a bit of tension for some time," a source close to 30-year-old John told Mirror.co.uk. "They initially opted for a break, hoping a trial split might make them stronger. Sadly it doesn't seem to have worked. John took the decision to end things as he felt he just wasn't ready for the level of commitment that Jennifer deserved."

The source went on to say, "Contrary to reports, Jen didn't want to have kids or marry this year, but she did want to set a timetable for their future together."

Since her divorce from Brad, Jennifer dated actor Vince Vaughn for a year. More recently she dated model Paul Sculfor.
