Did John And Jen Break Up Again?

Surely we're not the only ones who are beginning to suspect that John Mayer and Jennifer Aniston have split up once again.

We had to open up the X17 archives to figure out that the last time we actually saw them together was nearly a month ago at dinner in Beverly Hills.

Everything looked fine at the time. They'd been going to premieres in New York and LA together - even jetting off to Cabo for a little fun in the sun. So what happened?!?

We emailed their reps for a comment, but unfortch they're not talking.

So what do you think is going on?
