The actress was apparently quizzed during her recent Greek holiday about rumours that she and Pitt are to wed at their French home, an eyewitness told Page Six.
The informant said: "Angelina was in white, but she laughed and said 'not yet' when the restaurant owner asked if she was getting ready to be married. She also said, 'We love Greece too much to leave... we have other islands to go to before heading back to France."
Jolie and Pitt were apparently joined on their holiday to Mykonos and Santorini by their children.
The couple announced their intentions to marry in April after Jolie was seen wearing an engagement ring at an LA gala.
Pitt later explained that his and Jolie's engagement was "something that made sense" to both of them at this stage in their lives.
