Kendall Jenner reveals that having children came later than she expected.

Kendall Jenner is 28 years old, but that's all relative, and in her world everyone is having or has had babies. Well, maybe not everyone, but all of her siblings have babies (Kourtney Kardashian Barker and Kim Kardashian each have four, Khloe Kardashian and Kylie Jenner have two, Rob Kardashian has one), and her best friend Hailey Bieber, yesterday, just announced her first pregnancy.

Jenner, the cover star of the latest issue of Vogue, said she is "enjoying the freedom of being childless," but admitted that she thought she would be a parent by now: "When I was younger, I used to say I wanted kids by 27. 'When I was younger, I used to say I wanted kids by the time I was 27,' she said. (She will turn 29 in November.)

However, having children someday remains a priority for her. She has recently been dating Bud Bunny, and this week raised eyebrows when it was revealed that the two, who were thought to have broken up, were getting cozy at the Met Gala after-party on Monday night. (Bad Bunny was one of the gala's four co-chairs.) "Relationships are very important to me," she said. And I can't wait to one day share my life with someone, have children, and start a family."

Jenner has been on the hit reality show since she was 11. Her family's first foray into the genre was in 2007, when "Keeping Up with the Kardashians" first aired on E! The family has now moved to Hulu with "Keeping Up with the Kardashians," but 17 years later, the supermodel admitted to Vogue that the show is "not my favorite thing. 'To be honest, I'm not very good at filming. To be honest, I'm not very good at filming."

In other parts of the candid and vulnerable interview, Jenner, who has long been open about her mental health and struggles with anxiety, told Vogue, "I remember having these meltdowns on the plane. It would come on so suddenly." Palpitations, shortness of breath, dizziness, double vision of things, creepiness. All of it." She called her mother, Kris Jenner, "crying hysterically," and said, "I want you to stop the plane. I want you to stop the plane. [Breathing exercises, distractions, meditation, journaling, and regular conversations with a spiritual healer are at the top of the list, as well as weekly sessions with a psychotherapist.

"A big thing I'm working on in therapy is feeling worthy of where I am and knowing that I shouldn't let what is being said about me on the internet, especially about my worth, get into my head too much," she said, especially Chloe added that she advised people to avoid nasty comments on social media to protect their own mental health." I let it get out there and I think that's what lets it down a lot of the time."

Another strategy for cultivating strong mental health is to get out of bed, "put one foot in front of the other," and get the "blood flowing," she said, adding, "When I say I'm suffering now, I'm not doing those helpful things. Choosing to sit in bed and mope all day is setting myself up for failure."

Jenner's Vogue cover came out yesterday, the same day Bieber announced her first pregnancy. Bieber appeared in Jenner's cover story, saying of her best friend. I really admire that about her."

She said, "I really admire that about her.
