The New York Post’s Page Six is speculating that Jessica Simpson and John Mayer’s burgeoning relationship might just be for the paparazzi.

The couple dined at Nobu in South Beach, Florida on Monday night and were snapped entering and leaving the restaurant. However a fellow diner told the newspaper the two “barely spoke”: “John was extremely quiet and didn’t speak a lot. [Jessica] just gave a lot of puppy-dog looks and twirled and twisted her hair.”

The onlooker added that the couple did hold hands for a while but then Jessica left John alone at the table for 20 minutes in order to “fixed herself up for the cameras” that followed the pair back to the Four Seasons hotel.

Jessica’s spokesperson Cindi Berger refused to comment on the rumours, saying: “I will not comment on her private life.”
