The Bourne Identity star Julia Stiles snubs the party lifestyle in glitzy Hollywood, because she fears her "mother would disapprove".
The former child actor used to juggle acting with English Literature studies at New York's Columbia University, and has behaved sensibly ever since as a result of her studious nature.
She says: "I wasn't really that close to my classmates - which helped me focus more in school.
"I certainly had fun but I was careful not to get out of control too much, because people are gossiping in college anyway.
"I don't think my mother would approve."
