One highlight of this year's event is the "Eggtivity Zone," in which athletes and coaches will help teach kids how to play sports. Among the stars scheduled to attend are Minnesota Vikings running back Adrian Peterson, NASCAR driver Danica Patrick, gymnast John Orozco and Washington Wizards point guard John Wall.
Two of the younger celebrities in Monday's lineup are Oscar-nominated actress Quvenzhane Wallis, star of "Beasts of the Southern Wild," and Robbie Novak, who plays "Kid President" in a series of popular YouTube videos. Elmo, Abby and other "Sesame Street" Muppets will also be performing.
