We know Kendall and Kylie Jenner have had their share of drama as sisters over the years, but we didn't know it went this far! ​In Kenny's cover story for the June issue of ​ELLE, she opened up on everything from anxiety, to how strange it is that her little sister had a baby before she did.

And she also opened up on a certain fight she had with Kylie, over their pal Hailey Baldwin!

Kendall, interviewed by Lana Del Rey, explained how she got close with then-Kylie's friend Hailey, and her little sister was not too pleased.

“She was actually best friends with Kylie, and I was good friends with her cousin Ireland [Alec Baldwin’s daughter]," Kendall shared. "Hailey lived in New York, and whenever we were there, we would hang out with her.” 

During Kendall’s first New York Fashion Week, she says she “stole Hailey from Kylie. From then on, she was my homie. At first, Kylie was mad; I had to bring them back together and be like, ‘No, it’s okay, guys.’ But it’s all good; that’s our love story.”

It's definitely normal for sisters to fight over friends, especially when they're so close in age. Kendall and Kylie are in all the same circles, so they'd better get used to sharing besties! It seems like they do a great job at it.
