Kendall Jenner thinks it's ''weird'' that her younger sister Kylie has had a baby before her.

The 20-year-old lip kit mogul welcomed her daughter Stormi - whom she has with her boyfriend Travis Scott - into the world three months ago, and whilst her older sibling believes Kylie is a ''beautiful'' mother, she can't help think that being a parent at her age is a bit bizarre.

Kendall said: ''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.''

But the 22-year-old model has credited baby Stormi with helping to bring her closer to her little sister, as she says Kylie is more ''loving'' now.

She added: ''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 toward me.''

The 'Keeping Up with the Kardashians' star also spoke about her struggle with anxiety, and says she was amazed when other celebrities told her they were going through the same problems.

Speaking to Elle magazine, she said: ''It's interesting; ever since I said something about being anxious, a lot of people in the spotlight have come to me, being like, 'Oh my God, me too!' There's this community. I take what they do to help themselves and piece it together to find what helps me.''

Kendall spoke about her mental health battle during an episode of her family's reality show which aired earlier this year, in which she said she is a ''hypochondriac''.

She said: ''Since I was a kid, I've always been a hypochondriac. I've always been the worst hypochondriac. But now I have to try and be a big girl.''

But the star is trying to stay positive and insisted she is getting better.

She said: ''Anxiety is all mental, so you have to try and find your ways around it. I try and maintain it, but sometimes it's out of your control. But I think I'm very blessed to be in the situation I'm in, and every year that I do fashion months it gets a little bit easier. It's really exciting. I still look forward to it every year.''
