Natalie is the oldest child of the late Joseph Robinette ‘Beau’ Biden III and his wife, Hallie. She is 16 years old and was featured in a clip introducing Dr. Jill Biden’s speech at the DNC on Tuesday night. "I would say she’s not your average grandmother," she said of her grandma, per Today. "She's a prankster, she's very mischievous. When she goes on a run, sometimes she'll find like a dead snake and she'll pick it up and put it in a bag and she'll use it to scare someone."
