“I’m constantly inspired by the determination in every single student at WE Day — the energy they bring is unforgettable,” says Gomez, who is a longtime supporter of WE Day and hosted the event last year. “This is my sixth WE Day and I can’t wait to share words of encouragement with thousands of young leaders who have accomplished so much worth celebrating. This generation is changing the world and I’m humbled to be a part of this special day with them.”

WE was founded by activists Craig and Marc Kielburger to motivate and inspire young people to create positive change in their communities, and WE Day is a series of 19 stadium-sized events held across the U.S., Canada, the U.K. and the Caribbean.

“We are surrounded by youth of the WE generation — a generation that is tuned-in to the needs of their community both globally and locally,” says Craig. “They have committed to choosing hope, optimism, empathy and courage over fear, division, apathy and intolerance. We are honored to celebrate young people from over 875 schools and youth groups from across California, who have joined together to make a difference and prove that you are never too young to change the world.”

The organization also helps provide schools and community groups with curriculum, educational resources and action campaigns through its educational program WE Schools.

The WE Day Special — which celebrates extraordinary youth, families and educators and is sponsored by The Allstate Foundation, Walgreens and Microsoft — will air Aug. 17 at 8 p.m. EST on ABC.
