Jennifer Aniston and John Mayer Heat Up Miami

Oh it's on! John Mayer flew to Miami on Wednesday and checked into the Mandarin Oriental...on the same floor as his rumored love Jennifer Aniston.

He immediately went to visit her on the set of her movie where the two "started making out," according to spies at the NY Post.

The new couple was also spotted playing tonsil hockey in a hot tub on Saturday, just hours before the "Marley & Me" wrap party.

Things are really starting to heat up for the couple. This is the third time Mayer has flown to Miami for Jenn in the last few weeks. What are your thoughts on the union?
