Matt Damon`s children unaware of his stardom

London: Hollywood star Matt Damon claims that his children do not know that he is a movie star as they are used to seeing themselves on screen as a result of new technology.The `Bourne Identity` star is grateful that technology such as iPhones and BlackBerrys are duping his younger children with wife Luciana, three-year-old Isabella and Gia, one, reported Contactmusic. "The little ones don`t have any idea - we`re trying to keep it that way. It`s more and more possible now with the prevalence of video cameras and technology, iPhones and BlackBerrys. Kids are used to seeing their own images on screens. So when they see me on a screen, it kind of makes sense for them: `Yeah, he`s on that TV and I`m on this laptop`," said Damon. But his 11-year-old step-daughter Alexia is well aware of the actor`s profession and has seen couple of his movies. "The 11 year old obviously knows. She hasn`t seen all the movies but has seen enough to know that`s what I do," said the 39-year-old actor. PTI
