Jodie Foster claims being a movie star can be "heartbreaking". The former Hollywood child star admits she finds it difficult to separate the character she's playing and her real life.The Oscar-winning actress said: "There is a whole bunch of stuff that I don't like to talk about. This is a sort of lonely experience of being obsessed and impassioned by film and you live it because you are doing it so many times a day." You have this huge well of feeling. Strangely enough, the thing that is really heartbreaking and really wells it all up is when the movie is released. When I look on the screen and I see the movie, it's not like I see a different person." Foster, 44, recently slammed Lindsay Lohan's mother, saying she was to blame for the young actress' well-documented drink and drug problems.The 'Silence of the Lambs' star claimed Dina Lohan has not been a good parent to Lindsay, who is currently being treated for drink and drug addiction in Utah's Cirque Lodge.Jodie said: "Can I just ask, where is her mother? I mean, really, where is her mother?"
