Brian Williams' Adorable Response To His Daughter's Casting In 'Peter Pan'

Parents always brag about their kids. If your dad is Brian Williams, though, he might brag about you on "NBC Nightly News."

On Wednesday night, Williams reported that his daughter Allison has been cast in NBC's upcoming telecast of "Peter Pan" in the role of Peter Pan. "Family members confirm that she's been rehearsing for this role since the age of three and they look forward to seeing her fly," he said. He then pulled up a photo of her as a kid in a Peter Pan costume.

Allison Williams, of course, stars in the HBO series "Girls." "Peter Pan" will air December 4. Brian Williams has talked about her career before, once joking that he and his wife watched the Grammys at home, while his daughter was there in the front row.
