John Mayer dumped Jennifer Aniston for the 27th time. They may be back together as I'm typing this.

Oh the drama............
Jennifer Aniston and John Mayer may have called it quits.

That's the rumor I'm hearing. A source says that the pair's on-again, off-again relationship may have ended when Aniston returned from overseas, where she was promoting Marley & Me. She returned sometime within the last week.

"He broke up with her when she got back from her European tour," the source said.

Aniston's rep did not immediately comment. Mayer's rep declined to comment on the singer's personal life.
