Jennifer Aniston JAnistonJMayerEXCLU1027_bu.jpg

We're hearing through the grapevine that Aniston and Mayer may be dunzo - again!

Everyone's talking about ...

... how JM's blog mentioned NOTHING about his supposed girlfriend and how they spent cuddling in front of a cozy fire during Thanksgiving, enjoying turkey and cranberry sauce ...

.. and how we haven't seen them together since Nov 19th ...

... and how X17 spotted Aniston solo yesterday ...

... and how it was obvious it'd never work out between these two anyway!

So whadaya think? Are these two still ON or OFF AGAIN?
