Now this sounds like quite the kiddy event. Jack Black - America’s current favorite man-child - will host the 2008 “Kids’ Choice Awards” (8 p.m. Saturday, March 29, Nickelodeon). The ceremony also will throw in performances from Miley Cyrus (see what happens when the Disney Channel unlocks her shackles?) and the Jonas Brothers, who, I have it on great authority, are cute.
