Jennifer Aniston IT19p001A1Jen.jpg

Or is it just another example of Pop Fiction?

John Mayer happily tells In Touch Weekly that "his weekend was good" - his weekend, that is, with Jennifer Aniston in Miami!

The two spent four days with each other, dining out at restaurants for long hours where onlookers say John was "very attentive to her," shopping arm in arm in town and spending time by the pool at Jen's hotel, the Mandarin Oriental. All the while, eyewitnesses note that the couple "were in their own little world. They couldn't stop looking at each other."

Can this really be happening? Jen's had her heart broken in the past and John's a bit of a player... think these two are right for each other?

We're just not sure!
