NEW YORK (AP) - It won't just be the Denver Broncos, Seattle Seahawks and the fans getting ready to deal with the cold at the Super Bowl. Bruno Mars says when he was rehearsing outdoors for the gig at MetLife Stadium in New Jersey on Sunday, "the microphone turns into a Popsicle." So, Mars is trying to get "some heaters on everything." Mars is one of the youngest stars in recent years to be asked by the NFL to handle the Super Bowl halftime show. And he says he feels "like a new artist" compared to some of the acts who've done the halftime gig.
