15 times the Kardashians were the definition of 'sister goals'

The INSIDER Summary:

• The Kardashians may fight and make fun of each other like a lot of sisters do.
• But at the end of the day, they are all there to support their family.
• The Kardashian sisters keep each other in check, especially when the fame gets to be too much.

Like a lot of sisters, the Kardashian-Jenners bicker, make fun of each other’s crying faces, slap each other with handbags, and take selfies when one of them is going to jail. Well, maybe not all sisters. But the point is that at the end of the day—after all the family turmoil and runny-mascara-eyed fights—the Kardashians are family.

There’s a reason that Kardashians have been reality television’s most-watched family for the last decade. Yes, their drama is juicy as hell, but another major reason viewers keep tuning in is because the Kardashians are sisters—and that’s one thing plenty of people can relate to.

Despite their millions of Instagram followers, the Kardashian women keep one another in check and can teach each other things that only big sisters can. Click through the gallery to relive 15 of the sweetest moments when the Kardashian-Jenners acted like the big sisters we wish we had.
