Kardashian momager Kris Jenner turned 60 last week, and the festivities were full of celebratory, heartwarming viral content. Her Great Gatsby-themed party lead to an unprecedented surge in glamorous 1920s Kardashian fashion Instagram photos, and her gift from her daughters needs to be seen to be believed. Because would you believe that the five Kardashian/Jenner sisters would make a singing parody of a video that Kris Jenner made on her 30th birthday? Can you believe anyone even made a video 30 years ago? Can you believe O.J. Simpson is in it? O.J. Simpson is in it!
