You see, not only is the 14-year-old psyched about the all-star event, but he's one of the featured performers, too! Greyson will be sharing the stage with Cody Simpson, Honor Society, Hanson, Colbie Caillat, Drake Bell and more, and you don't have to leave the comfort of your home to watch it.
Fans can get full access to the event by signing up to watch the Rock the Red Kettle concert here. As an added bonus, you'll be automatically entered for a chance to win a trip for two to L.A. when you register. How cool is that?
Check out Greyson's personal message about Rock the Red Kettle below, and make sure to get in on all the action by signing up to watch the show on December 17 at 5PM PT.
