The Kardashians may have taken over reality TV just a few years ago, but the celebrity family has been filming their day-to-day lives since the '80s!

Kim Kardashian was feeling very nostalgic and posted old photos and home videos from her childhood onto her Facebook page. Many of the home movies include Kim and her big sis Kourtney singing and dancing for their late father Robert Kardashian -even then they loved the camera.

In several interviews, Kim has admitted to copying Kourtney while they were growing up. Although the sisters no longer wear matching outfits and hairstyles, some things just never change. In the adorable home video below, Kim and Kourtney are wearing makeup. Kim starts developing her glamorous traits in one video where the girls are wearing masks but she takes hers off because she didn't want to ruin her makeup.

Now, there are new babies in the family: Kourtney's children Mason Disick, 2, and Penelope Scotland Disick, 2 months. Kim is rumored to be having one on the way after photos of her with a round belly surfaced the web. Little sister Khloe Kardashian, who is married to NBA baller Lamar Odom, just made three years with her husband and is still trying for a baby.

The Kardashian family is ever-expanding. We're sure there will be more mini-Kardashians on the way soon. Until then, enjoy the vintage photos and Ghostbuster dance-marathon videos of the tiny Kardashians.
