Giuliana Rancic's 6-year-old son hilariously crashes her 'E! News' broadcast

After making her return as an 'E! News' co-host earlier this month, on Thursday Giuliana Rancic took her 6-year-old son, Duke, along to the set for some fun. And he had loads of it: He operated a camera, wore a crazy hat, and ran around backstage and on the set. But when it was time for mama to hunker down and work, Duke was way too excited — and crashed the show.
