John Mayer johnjen.jpg If music be the food of love, then Jennifer Aniston's gonna be chowing down at the wrap party for Marley & Me - where her new man John Mayer's been booked to play a quick concert!

In Touch Weekly is reporting that Mayer is slated to perform three songs at the party, currently scheduled for Saturday, May 10th. Initially, the party was set for tomorrow, but John pleaded with the organizers to push it back for a day. "Everything was changed last minute so John could do this for her," an insider told the mag. "He's crazy about Jen."

Other insiders went on to expound on John's newfound love for Jen, describing their relationship as "hot and heavy - but in that very cool way" and stating that "John isn't going to hide his adoration and he's telling everyone what a cool chick Jen is." Of course, just a few days ago folks were wondering whether the couple had already called it quits - guess they must have smoothed things over, and we couldn't be happier for them both!
