Anne Hathaway, Ian Somerhalder and Jenny McCarthy have joined the battle against high school bulling by filming a new public service announcement (PSA) following a spate of teenage suicides across America.
Kristin Cavallari and Julie Benz also get serious in the video for The Trevor Project, a non-profit group dedicated to helping youths who are struggling with their sexuality.
The video comes at a time when America is coming to terms with a number of suicides linked to sexuality and bullying - the most recent, the death of 18-year-old Tyler Clementi last week (begs27Sep10), sparked outrage after it was revealed his college roommate allegedly posted footage of him having sex with another man online.
And the celebs are urging troubled teens to seek professional support if they are being targeted.
Hathaway says, "It gets better. If you or a friend are feeling lost and lonely there's someone who can help. There is hope and there is help. Call The Trevor Project."
The Hills star Cavallari adds, "If you're being bullied in school, you're not alone. Don't give up."
