Jennifer Aniston is "falling in love" with singer-songwriter John Mayer, according to a report.

The 39-year-old actress was spotted on a romantic dinner date with Mayer, 30, last month in Miami, where she is currently filming her new movie Marley & Me. They have also been seen cuddling up together on a sun lounger at Aniston's hotel on South Beach.

A source close to Aniston told the Daily Mail: "She's really into John, and the nine year age difference doesn't bother her for a second. Jen's already telling friends she's falling in love with this guy."

Though Mayer has since returned to New York, the pal added: "Jen's really hoping he can spend more time in Miami with her. She just wants to see a lot more of him. This was definitely not a one-off thing as far as she's concerned."
