One week after their secret on-set rendezvous in Miami, John Mayer and Jennifer Aniston have finally gone public with their romance.

In photos posted on X17's website, the new couple show off their couple-hood as they frolic in the pool of the exclusive Mandarin Oriental Hotel in Miami on Saturday. And according to witnesses, the couple did more than just a little splashing around in the water, as they locked lips in full sight of other hotel guests.

This is only the latest development in Jen and John's blossoming relationship, which first came to light last month when the camera-friendly couple spent several days together dining and sunning in and around Miami, where the former Mrs. Brad Pitt is filming Marley & Me with Owen Wilson.
