Are actress Jennifer Aniston and singer John Mayer really dating or is this just the latest in a string of rumored hookups for the actress? Let's be honest, John, 30, changes girlfriends faster than most of us change our socks, but Jennifer, 39, is a bit more reserved.
Since splitting from Brad Pitt, she has only had one semi-serious relationship and that was with Vince Vaughn. Other than than that, it's been fairly quiet on the romance front for Jen. Still, that hasn't stopped the tabloids from linking her to everyone from Owen Wilson to Orlando Bloom.
After a private lunch at Michael's Genuine in Miami, Jen and John made their way over to Casa Tua on South Beach for an intimate little dinner. Could these two really be heating up or are they simply making plans for Jen to star in John's next music video?
