Nobody balls harder than Y100's Jingle Ball. And this year's yuletide lineup — led by elfin party host Justin "Lil Swaggy" Bieber — is bigger, better, and ballsier than ever. The 2012 edition of Clear Channel Communications' festive pop superfest is straight stacked with Top 40 phenoms: Flo Rida! Psy! Ke$ha! Enrique Iglesias! One Republic! Fun.! Afrojack! Zedd! And six other ballerific stars! Plus, sponsored by Kellogg's Krave ("a new breed of chocolate cereal"), South Florida's favorite annual holiday megaconcert is guaranteed to be just as hyped-up as a caffeine-addicted tween. So giddyup! Go ask Santa and Mama Claus for some tix. Then jingle all the way to the BB&T Center in Sunrise. Oh, what fun it is to ride and sing a ballin' song tonight!
