It seems that torturing wannabe singers with backhanded compliments and full-frontal insults just isn't enough for Simon Cowell and American Idol producer Ken Warwick. Starting April 6 in L.A., they'll be conducting casting calls nationwide for a new NBC reality show called America's Got Talent. "We are looking for performers of all ages in every talent category in hopes of finding that next big name in lights," Warwick tells the Associated Press. Adds Cowell: "This is the show I've always wanted to make." (Funny — I thought that show was Cupid.) Gluttons for punishment can get audition details by visiting www.nbc.com and clicking on "casting."
