She also opened up about how motherhood has changed Kylie.
This is Kendall and Kylie Jenner, although let’s face it, they don’t really need an introduction.
You may be aware that back in September last year it was reported that Kylie Jenner was expecting her first baby, and everyone was shocked and excited in equal measure.
Then, in February this year she gave birth to a baby girl named Stormi and the world was shocked all over again.
Well, now Kendall has opened up about how she felt about Kylie having a baby – and it turns out she was also pretty surprised.
In fact, speaking to Elle, Kendall revealed that she found it “weird” when Kylie announced her pregnancy.
It's obviously a bit weird that your little sister is having a baby before you. I didn't expect it to happen like this. But it's beautiful.
However, she went on to say that their relationship has only strengthened as a result of Kylie having a baby.
It's brought us closer together. We've always been very close, but we would butt heads all the time. This has made her a bit more loving towards me.
And Kendall also addressed the fact that the Kardashian/Jenner family has grown at an unprecedented rate recently, what with Kim, Kylie and Khloé all having babies within months of each other this year.
She said: “It's forever growing. Every time I think it's eased up, someone's popping out a baby.”
