Rocker Pete Wentz has signed up to be a part of the #PostItForward campaign, which has just launched on popular blogging platform Tumblr.

This exciting new initiative aims to encourage teenagers to share a video, in which they open up about their own personal struggles with hardships such as bullying, mental health issues, sexual assault and self-harm, as a way to show their contemporaries that there are others going through similar problems and that there is support available.

In the Fall Out Boy superstar's promotional video, he explains: "Nobody is perfect. It's okay to ask for help. Whether you're dealing with bullying, mental health or self-image issues, know that there's no shame in talking about what you're going through.

Film star Elizabeth Banks, singer Jordin Sparks, chat show host Wendy Williams, and U.S. Vice President Joe Biden have also all shared their experiences for the #PostItForward campaign.
