Right on the heels of her sister comes Pixie Geldof, meaning that the children of Paula Yates are now tied with the family of Jamie Oliver on four entries each. By comparison to the raucous Peaches, Pixie Geldof has led a more demure and reserved life. That doesn't mean she hasn't been active though; the 28-year-old is a model, singer, and activist, often lending her hand to environmental causes. She has a particular affinity for sharks.
As with Peaches, 'Pixie' isn't too out-there as a name (singer Pixie Lott would agree with that), but it's still something we'd expect to hear as a nickname more often than as a real name. Pixies are small and cute - appropriate for a child when it's very small but less so as they get older. To make things worse, her actual birth name was even worse - she's since dropped it, but she was once 'Little Pixie Geldof'!
