According to sources Simon Cowell will be back in front of the cameras for "America's Got Talent" next season. NBC confirmed on Tuesday that Cowell, who created the UK version of the show, is returning for his second round as a judge. NBC Entertainment Chairman Robert Greenblatt said that Cowell's addition has boosted the panel's chemistry. He then added the talent show itself is drawing more viewers this summer than over the last five seasons. Cowell will be reunited with Mel B, Heidi Klum and Howie Mandel on the program's judging panel. Nick Cannon will also be back as host.
