American Idol 's producers are moving on from regular pop-star wannabes and will next be showcasing the offspring of celebs, the New York Post says. The show, tentatively titled Rock the Cradle, will feature a lineup of celeb spawn singing their way to stardom in an Idol-like format that will air on MTV. While a formal announcement about the show will be released next week, the show's participants have not been fully nailed down yet - although Art Garfunkel's 17-year-old son, James, is one of the potentials. AI's producing company, Fremantle, and MTV have quietly been working for months on the details. We can only cross our fingers that the celebs' spawn have as much star power as their parents to entertain us for a whole season. - Anna Dimond
