A Toronto teen and anti-bullying advocate will join pop superstar Lady Gaga on Wednesday as she launches her Born This Way Foundation at Harvard University.

Jacques St. Pierre, a 17-year-old student at Etobicoke School for the Arts, will attend the official launch of the anti-bullying foundation, which Lady Gaga and her mother started in 2011.

St. Pierre was handpicked by Lady Gaga after he contacted her for an anti-bullying rally at his school, where he is student council president. She replied with a video, which was played at a school assembly in November.

St. Pierre has also founded his own anti-bullying project, called "I will make it better."

"I'm proud of the fact that we're really making a difference," St. Pierre said. "And I think I never believed or thought that it would become this huge and people would really start to listen. … People are starting to open their eyes and pay attention to the issues surrounding bullying, and I think it's fantastic that we can be the ones to really lead that change and help make it better for kids all over the world."

There will be a number of workshops and a keynote speech from Oprah Winfrey, St. Pierre said.
