Think celebs don’t see the great work you do? Think again! Justin Timberlake, Hayden Panettiere, LeBron James, and Alicia Keys will appear on the upcoming TeenNick HALO Awards, an hour-long show that celebrates four real teens who are making a difference in the world. Each teen was surprised with a visit from one of the celebs, a grant for their organization, and scholarship money. The show, hosted by DoSomething.org friend Nick Cannon, airs on December 11 at 8 pm Eastern Time on TeenNick. Check out the preview below.
