Jenna Bush (1981-)
Daughter of Laura and George W. Bush, Jenna worked as an intern with the United Nations Children's Fund (UNICEF) and published a book about that experience called Ana's Story. One of the stops to promote the book was on the Ellen Degeneres Show, where Ellen convinced Jenna to call her parents during the interview. Jenna joked, "I'm not going to get anything I asked for for Christmas." Ellen reassured her, "We're not barging in while they're in their pajamas or something."
Fun Fact: Jenna's secret service code name was Twinkle.
