The actress brought teenagers who were affected by recent shootings to the Teen Choice Awards stage and asked the crowd to help end to gun violence.

The biggest news coming out of the Teen Choice Awards last night was not the fact that Jennifer Lawrence and Josh Hutcherson took home the prize for Best Liplock. It was that a bunch of celebrities took a break from handing out those coveted surfboards to stop being polite and start getting real.

There was Justin Timberlake's speech about unity inspired by Muhammad Ali, Jennifer Garner's message of hope for sick children, and a mock presidential election that featured cohosts Victoria Justice and John Cena decked out as Hillary Clinton and Donald Trump while the audience voted on our country's next president. (Spoiler alert: Hillary won.)

But the most poignant moment of the evening had to be when presenter Jessica Alba stepped up on stage to ask the crowd to help put an end to gun violence, introducing a group of teenagers whose families were affected by the shootings in Dallas, Orlando, Newtown, and San Bernardino.

"Many of those impacted by these acts of violence are teens," Alba began. "Tonight, we stand united in our call for peace. Now more than ever, we need to stop, feel, and ask what's going on."

Her moving tribute then gave way to singer Ne-Yo, who performed Marvin Gaye's "What's Going On" before an audience of teens waving lit-up cellphones.

"We need to come together as one," Ne-Yo told the crowd. "Now, if you feel as we do that we have to do better, I need you to stand up right now and take out your phones. Come on. All over the place."

He and Alba then asked the audience to take a picture of the teens onstage and post it to social media using the hashtag #StopTheViolence—which pretty much started trending on Twitter right after.

It's always an amazing thing when celebs use their star power for good. If you missed the performance, you can catch the whole thing here.
