Jennifer Aniston thinks John Mayer is "better looking" than Brad Pitt

Jennifer Aniston thinks new beau John Mayer is "better looking" than her ex-husband Brad Pitt.

The former 'Friends' actress, who spent four days in Malibu with the 'No Such Thing' hitmaker last week, is smitten with John and is enjoying their "passionate" relationship.

A source close to Jennifer said: "She says he is the cutest guy she has ever gone out with -- even better looking than Brad.

"There is nine years difference between them, though they are thriving on that. John likes her intelligence and experience and Jennifer likes John's vitality. Jennifer likes his energy, it is very uplifting for her - she is on cloud nine."

Jennifer, 39, is already beginning to think that 30-year-old John could be 'The One' and is making long-term plans.

The source added: "It is too early to tell if it will last. But they really, really like each other. John makes Jennifer feel sexy again."
