Portman: 'Childhood friends ground me'

Natalie Portman has said that regularly spending time with a group of childhood friends keeps her grounded.

The Star Wars actress takes a group of old school friends to parties and premieres, as she believes they help her make the right choices.

She explained: "I always make sure that anytime I go to a Hollywood event I have five school friends with me, because they're like my monitors. They're like, 'That person's nice, that person's not. That person won't even look me in the eye or shake my hand to say hi.'"

"You sort of see how these people are by how they relate to people around you. With me, everyone's like, 'Hey, how are you?' Like, super over-exaggeratedly sweet."
