A party fixture and writer, Bettina is an inescapable presence on the social scene.

A Princeton grad, Kilkha was raised in New York by parents who founded the first private bank in the Middle East. Although she started her career in advertising, Kilkha found her career path when she began writing about fancy parties and style rather than just attending them in fabulous clothes. Her first book, 2004's Ultimate Style: The Best of the Best Dressed List, and her contributions to E!'s 101 Most Sensational Crimes of Fashion have transformed Kilkha as somewhat of a style authority, and she's found steadier gigs as a contributing editor at FashionEtc., with her column "Bettina's Take" and a special projects editor at Elle Decor, where she writes the "RSVP" column. However, she also fills her evenings by hitting up the most posh parties and events in the city. [Image via Getty]
