Jennifer Aniston and John Mayer in Miami

Michael's Genuine Food & Drink in Miami's Design District was the setting for a late lunch date between Jennifer Aniston and John Mayer. The duo arrived after the restaurant had closed between lunch and dinner hours at around 3:30 p.m., but Charles Bell, general manager says, "I was happy to accomodate them."

During their 90-minute meal, Jen, 39, who is in town filming Marley & Me ordered the chopped chicken salad while John, 30, enjoyed a Serrano ham sandwich. The meal didn't end there as the two shared a chocolate-and-peanut-butter layered dessert.

While this could have just been two friends meeting up, witnesses say it looked like more than just a friendly lunch. "They were sitting across from each other, but were talking very close in deep conversation."

Later that evening, the two met up for dinner at Casa Tua on South Beach. Think love could be on the menu for these two sexy stars?
