It’s no secret that the Kardashians are a tight-knit family — and it looks like Dream and Reign are best of friends (we hope they include one-year-old Saint, too)! It’s no secret that Kourtney’s four-year-old daughter and Kim’s three-year-old are more than just cousins — they are total BFFs!

This is one family we definitely wish we were part of!
