John Mayer and Jennifer Aniston Break Up

andhave called it quits after a four month whirlwind romance. What started out as a "break," (how Rachel and Ross), has turned into a full break up according to sources.

The split is being reported by the UK tabloid the Mirror, so since we haven't been able to confirm with Jen or John's reps, we'll just let you know what the Mirror has to say.

According to the rag-mag, unlucky-in-love Aniston has been dumped by Lothario Mayer because he is just not ready for a commitment. Their "source" says Jen was pushing to set a timetable for their future together, and wanted John's assurance that he would cut down on touring when they started making babies.

Ironically Aniston recently completed filming "He's Just Not That Into You."

Consider the source kiddies and remember we are talking about the Mirror here. But if the rumors turn out to be true, rest assured we at Bitten and Bound will be on top of it and let you know.
