Mars will perform Sunday at MetLife Stadium in East Rutherford, N.J., where the Seattle Seahawks will play the Denver Broncos. The Red Hot Chili Peppers will join him onstage.
Mars' hits include "Locked Out of Heaven," ''Grenade" and "Just the Way You Are." He won the best pop vocal album Grammy Award for "Unorthodox Jukebox" this week.
