The Keeping Up With The Kardashians ladies have bagged their first six-piece cover of the Novemeber edition of the Cosmopolitan magazine for the first time in years. And the Kardashian sisters – all bar supermodel Kendall Jenner, 19 – were present and correct on Monday night for the magazine’s 50th anniversary celebration in Los Angeles. And while Khloe, 31, Kourtney, 36, and Kim, 34, united with their 59-year-old mother Kris Jenner in glamorous black ensembles, the littlest of the bunch, 18-year-old Kylie, bucked the trend in a thigh-skimming little white dress.
