KEYS, LEBRON HELP HONOR CHARITABLE TEENS: Celebs to honor real life teenagers at the inaugural TeenNick HALO Awards.

       The entertainers will pair up with four real-life teenagers who give back to their communities in various ways: An AIDS education organization, an ocean research advocacy group, a community improvement project to turn teens away from drugs and gangs, and a support group for girls with scoliosis, reports People.com.       

       "One person can make a difference, and it's my hope that this special will encourage ongoing activism and inspire a new generation of leaders," says creator and host of the show, Nick Cannon.       

       Additionally, each honoree gets to meet and work with their corresponding star, based on the celeb's own charitable interest. (Timberlake, for example, works with The Shriners Hospitals for Children, so he'll be teamed with Leah Stotz, who founded the scoliosis education and support group.)       

       The awards ceremony will air on TeenNick Dec. 11 at 8 p.m.
