Lynsey and Lisa Addario join Kate and Oliver on this week's episode of "Sibling Revelry." Lynsey is an American photojournalist who works with The New York Times, National Geographic, and Time Magazine, and Lisa is a writer and director for film and TV. They talk about growing up with four sisters, the wild pool parties their parents would throw, the family hairdressing business, what happened when Lynsey was kidnapped abroad (twice) and much more.
