The Kardashian ladies are cashing in on their reality TV fame with a string of unglamorous endorsements. But Kim’s star is rising faster than that of her sisters. She’s quickly emerging as one of social media’s biggest icons, and as she turns 30, Kim seeks a more equal partnership with her mom, Kris Jenner. Then she dives into a whirlwind engagement with basketball player Kris Humphries. Both Kim and Kris know the wedding can pull Kim from B-list celebrity onto the A-list, and they plan to profit from it. But this very public relationship will cost Kim her credibility — and could damage her career forever.
