Kim Kardashian, Khloe Kardashian and Kourtney Kardashian

Watch Justin Bieber, Katy Perry & Kanye West Cameo in a Kardashian Family Music Video Tribute to Kris Jenner

The Kardashians love celebrating: birthdays, holidays, baby showers, weddings -- they take all of them to the next level . So to commemorate Kris Jenner's 60th (which was over the weekend), not only did the famous family host a star-studded blowout, they also prepared a special gift for the Kardashian matriarch: a remake of her YouTube-famous 30th birthday music video called "I Love My Friends."
