Bruno Mars
When halftime rolls around at Super Bowl XLVIII, it's safe to say Bruno Mars won't be worried about the score. "Hawaii doesn't have a team, so I bounce around," says the Honolulu native. "I go for the underdog." That term hardly describes Mars, who will play the halftime show in the tradition of Paul McCartney, U2, Michael Jackson and other music legends. Mars is the first artist in 10 years to headline before turning 30, but he's already got two platinum albums and 14 past Grammy nominations (including one win), with four new ones this year. His best preparation for the upcoming performance at MetLife Stadium may have been hosting Saturday Night Live in 2012, despite having about as much experience with sketch comedy as Hawaii has with snow. Says Mars: "You gotta be fearless, man. … If I'm ever gonna sing in a blizzard, it may as well be at the Super Bowl."
