Why They're Hot: The New Boyz broke onto the scene in early 2009 with their hit song "You're a Jerk," and helped front the "Jerkin'" global dance craze. The dynamic So-Cal duo is prepping the release of their sophomore album, "Too Cool to Care," due later this year, and their latest single, "Break My Bank," is currently at No. 63 on the Hot R&B/Hip-Hop Songs chart and climbing. The Boyz also recently wrapped filming a movie directed by Mario Van Peebles called "Where Da Party At?" which is getting large comparisons to the 1990's Kid 'n Play flick "House Party."
