When Ryan Seacrest, the “busiest man in Hollywood,” touches something in the entertainment world, it usually turns to gold. But it seems the “American Idol” host, radio personality and producer of such mega-hits like “Keeping Up with the Kardashians” and the Emmy Award-winning “Jamie Oliver's Food Revolution” missed the mark this time. The new Seacrest-hosted reality TV show “Knock Knock Live” was pulled by Fox after just two episodes, Variety.com reports.
