Star Magazine is reporting the not only is Jennifer Aniston pregnant with John Mayer’s baby - but that she’s having twins! I don’t know whether to believe this or not, but time after time these magazines tend to be onto something.

According to the mag, Jen has been undergoing fertility treatments and trying to get pregnant by the time she turns 40. The actress has been snapped recently reuniting with her former flame, John Mayer - and also covering her growing stomach.

“She knows her baby-making years are limited,” says a source told the magazine. “It’s hard for her to think of anything else — she has babies on the brain!”

Time will tell…
