Katherine Kennedy

Katherine Kennedy, 27, is essentially the face of the Prevent Cancer Foundation, which means she spends almost all of her hostessing muscle on anything having to do with the foundation. She will occasionally branch out for truly worthy causes (see below), and her exclusivity coupled with over 9,000 loyal twitter followers make her the ultimate get for DC host committees. Host obligations: The Prevent Cancer 5k every fall; Ocular Melanoma Foundation events (her boyfriend Grant's project); and the Woodrow Wilson House galas, including their annual Spring Garden Party. Day Job: Director of Availor Philanthropy [Photo by Ben Droz]
