What do you do when you are the anchor of NBC's Nightly News and you have to report on your famous daughter? Well, if you are Brian Williams, you remain completely professional with just a hint of emotion. On Wednesday evening, the anchor had to address the news that his daughter, Girls star Allison Williams, had been cast as Peter Pan in NBC's upcoming Peter Pan Live. Brian kept his cool while talking about the news but added, "Family members confirm that she's been rehearsing for this role since the age of 3, and they look forward to seeing her fly." It's that last line that really gets us! Check out Brian above.
