The actress took the stage at the Los Angeles prizegiving alongside 10 teens who have been affected by deadly shootings across the U.S., including incidents in Orlando, Florida, Newtown, Connecticut, Baton Rouge, Louisiana, and San Bernadino, California.

After Jessica introduced each of the individuals next to her, she said, "It keeps happening and it has to stop. Many of those impacted by these acts of violence are teens... Tonight we stand together with these teens united in our call for peace and an end to this violence. Now, more than ever, we need to stop, feel, and ask, what's going on?"

R&B singer Ne-Yo then sang a powerful cover of Marvin Gaye's anthem What's Going On, as photos of gun violence victims and their families flashed on a screen behind him.

After the performance, a clearly emotional Jessica struggled to hold back her tears as she said, "These teens had the courage to come here and share their grief and take a stand. And tonight, Ne-Yo and I and all of us here and all of you watching need to do the same."

"We need to come together as one. We have to do better," Ne-Yo added, before asking everyone at The Forum to take out their cell phones and snap a photo of everyone on stage, and post it to social media with the hashtag "#StopTheViolence" to help bring awareness to the issue.
