Keeping up With Kim Kardashian

Sorry, Kourtney and Khloé, but Kim is the most popular — and most in-demand — Kardashian sister. The curvaceous reality star dabbles in pretty much anything that will guarantee her more time in the limelight: She models, acts, produces, and writes. She's also opened and run DASH boutiques in Los Angeles, Miami, and New York; appeared in Season 7 of Dancing With the Stars; penned a book with her sisters (Kardashian Konfidential); and created a jewelry line, clothing line, and sunless tanner — also with Kourtney and Khloé. In an oh-so-shocking twist, Kim is looking to round things out by launching a singing career. Finally, as further proof that you can't be famous without a sex tape, Kim stars in a no-longer-private porno with her ex-boyfriend Ray J.
