Things are heating up between Jennifer Aniston and John Mayer since their steamy weekend in South Beach last month. According to In Touch magazine, John's planning to perform at the upcoming wrap party for Jen's new movie Marley & Me.
The soiree isn't until Saturday, but Life & Style reports the rocker's already back in Miami and shacking up at the Mandarin Oriental hotel, where Jen just so happens to be staying.
The party was originally set for Friday, but everything was moved around so her man could have plenty of time to prep for the performance. He's reportedly set to perform three songs at the Nikki Beach bash.
"It's hot and heavy, but in a very cool way," says a source. Sounds like it—even if the two aren't serious per se, Jen's getting some serious benefits out of being John's friend.
