London, Aug 13 : After weeks of whirlwind romance, Jennifer Aniston has been dumped by her rock singer beau John Mayer, say reports.
The pair initially decided to spend some time apart, before making the break official.
The news of the split with Gravity singer John comes just weeks after the couple were rumoured to be considering marriage.
"There's been a bit of tension for some time," the Mirror quoted a source, as saying.
"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.
"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.
"She also wanted him to assure her he would cut down his tours in the future when they did eventually have children.
"Initially, Jennifer was furious when he told her of his decision but now she's simply sad - not to mention a little heartbroken. They have spoken on the phone since the split and are trying to remain on good terms.
"But unless John has a dramatic change of heart, it's unlikely they'll rekindle their romance," the source added.
