Jonas Brothers Make A Surprise Appearance At We Day

Nick, Joe and Kevin Jonas let their smiles shine as they perform at We Day: A Youth Empowerment Event held at The Air Canada Centre in Toronto on Monday afternoon (October 5).

According to the Canadian Press, the musical trio were on the taped message that was broadcast but then stepped out on stage moments later — bringing the audience to their feet.

Almost 16,000 student leaders were at the event organized by Free The Children today and is aimed at celebrating the power of young people to change the world.
