Pop star Ashlee Simpson, hip hop artiste Fergie and actress Brittany Snow have signed up for the Seventeen magazine Body Peace Project, a treaty to change young girls' perception of their bodies.

The three women want teens to stop being obsessed with their bodies. The magazine's editor-in-Chief Ann Shoket launched the project to help girls develop positive attitudes towards their bodies, contactmusic.com reported.

Snow recently revealed that she suffered from anorexia and bulimia and now wants to help young girls who are struggling with similar issues.
