Kylie Jenner Age 2026: How Old Is Kylie Jenner?

Last updated: October 4, 2026 · By Nathan Cole

Kylie Jenner is 29 years old. She was born August 10, 1997 in Los Angeles, California, and turned 29 on August 10, 2026 — about eight weeks ago. That makes her the baby of the Kardashian-Jenner clan, though the word “baby” stopped applying somewhere around the point she sold half her cosmetics company for $600 million.

The number only tells a fraction of the story. Kylie was 10 when reality TV cameras started following her, 18 when she put $250,000 of her own savings into lip kits, 20 when she became a mother, and 21 when Forbes put her on its cover as the youngest self-made billionaire — a title it took back a year later. At 29, with two kids, a fortune estimated at $670–700 million, and a three-year relationship with actor Timothée Chalamet, she told Who What Wear in August that she can feel “the clock is ticking” as 30 approaches. This is the full age-by-age account.

How Old Is Kylie Jenner in 2026?

Kylie Jenner is 29 years old as of October 2026. The arithmetic is short: born August 10, 1997, she turned 29 on August 10, 2026 and will turn 30 on August 10, 2027.

That makes her the youngest of the Kardashian-Jenner siblings by a wide margin. Older sister Kendall Jenner (born November 3, 1995) is 30, while half-sister Kim Kardashian (born October 21, 1980) is 45 — a 16-year gap. The “baby of the family” label stuck even as she outpaced most of them in business: her $670–700 million estimated fortune makes her the second-richest in the family, behind only Kim.

When Is Kylie Jenner’s Birthday?

Kylie Jenner’s birthday is August 10. Born in 1997, that makes her a Leo — which her fans quote back at her every August alongside the usual jokes about Leo confidence.

Her 29th birthday, in August 2026, was a full production. She threw a “Princess Kitty” pre-party at her Beverly Hills home on Saturday, August 8, two days before the actual date — wearing a hot-pink latex dress, a pink feather boa, and a feathered crown, per Just Jared. Guests included Kendall, Kim and Khloé Kardashian plus Hailey Bieber; everyone dressed in pink. The spread featured at least two cakes, one gemstone-covered and one with frosting cats reading “Happy Birthday Kitty Kylie.” Her own Instagram caption: “Happy bday eve to meeee. i had my dream princess kitty bday night.”

One absence set fan forums buzzing: longtime best friend Stassie Karanikolaou didn’t appear in the photos. Tyla reported she was traveling in Europe with influencer Alix Earle at the time, and sources told gossip account Deuxmoi there was no falling-out — Stassie commented “Perfect girl, I love you forever” on Kylie’s post. Notably, the two were photographed together again at Sushi Park in West Hollywood on September 29, 2026, closing the speculation loop.

Kylie Jenner’s Age at Every Career Milestone

No other public figure compressed this much into one decade. The table below maps her age to each turning point — the fastest way to grasp how young she was when the big things happened.

The 0,000 Bet She Made at 18

In 2015, at 18, Kylie put roughly $250,000 of her own savings into three shades of lip kit. In her spring 2026 Vanity Fair cover story she described what that number meant at the time: it was, in her words, “probably, like, half the money I had in my bank account.” The kits sold out in seconds. Within a year the company had rebranded as Kylie Cosmetics, and the teenager from Calabasas was running what would become a nine-figure business from her phone.

Context matters here. Plenty of celebrities license their names to beauty lines; Kylie funded the first production run herself, which is why she kept the equity that later made her rich. The $250,000 figure is hers, on the record in 2026 — not a tabloid estimate.

Billionaire at 21, Retracted at 22: The Forbes Saga

At 21, in March 2019, Forbes named Kylie the youngest self-made billionaire in the world — a claim she herself qualified at the time, telling The New York Times: “I can’t say I’ve done it by myself… I have had a lot of help and a huge platform.” Eight months later, at 22, she sold 51% of Kylie Cosmetics to Coty Inc. for $600 million in November 2019, a deal that valued the brand at $1.2 billion. She kept roughly 44% of the company.

Then came the reversal. In May 2020 Forbes retracted the billionaire title, alleging the family’s accountants had overstated revenue and that the business was materially smaller than presented. Kylie’s camp disputed the accounting; Forbes recut her fortune well below $1 billion. An April 2026 Investormint review of the numbers called her current position “the $670M reality check” — noting that the gap between the $125 million and $360 million 2018 revenue figures at the heart of the dispute “is not a minor discrepancy.” She has not been re-listed as a billionaire since, though some outlets float estimates as high as $1.4 billion; those are outliers against the mainstream consensus.

A Mom at 20: Stormi’s Birth Changed the Timeline

Kylie was 20 years old when her daughter Stormi Webster was born on February 1, 2018 — fathered by then-partner, rapper Travis Scott. She kept the entire pregnancy off social media, a near-impossible feat for someone with hundreds of millions of followers, and announced the birth days later.

She has talked about young motherhood with unusual candor. In a British Vogue interview she reflected: “I come home and my kids just love me unconditionally… They’re just obsessed with me, and that’s taught me to walk through life a little easier.” She added that parenthood exposed her own selfishness: “I don’t think we realise how selfish we are as human beings until we have children.” Sister Kendall has said publicly that Kylie “had to grow up quick” because she became a mother at 20 — which is also, per Kylie’s own 2026 interviews, why her late twenties feel like a reclamation of the youth she skipped.

Kylie Jenner’s Kids’ Ages in 2026

Both children were born in February, almost exactly four years apart. Stormi arrived February 1, 2018 (Kylie was 20); Aire Webster arrived February 2, 2022 (Kylie was 24). In October 2026, Stormi is 8 years old and Aire is 4 years old. Both carry the Webster surname — Travis Scott’s legal last name is Jacques Webster.

Kylie has said she wants her children to have a different childhood than hers. Speaking to Vanity Fair in spring 2026, the then-28-year-old said her priority was “traveling with my kids, enjoying my kids” — noting that she was nine or ten when the cameras arrived, and that Stormi, now 8, is nearly the age Kylie was when she lost her privacy. She has also hinted she may expand the family further in the future.

Who Is Kylie Jenner Dating in 2026?

Kylie is dating actor Timothée Chalamet. The relationship began in 2023 — over three years ago — and they remain one of Hollywood’s most-watched couples, appearing together at the Oscars, the Met Gala, and the Golden Globes. After his viral Critics’ Choice Awards moment in early 2026, when he openly professed his love for her on stage, Kylie discussed the relationship in her Vanity Fair spring cover story.

Before Chalamet, her significant public relationship was with Travis Scott (2017–2022, with an on-off stretch into 2023), the father of both children. Earlier, she dated rapper Tyga (2014–2017). She has never been married — a common search misconception, since she shares two children with Scott.

How Tall Is Kylie Jenner?

Kylie Jenner is commonly reported as 5’6″ (168 cm). That is the figure used by mainstream entertainment outlets and the one you’ll see in most 2026 profiles.

There is, however, an honest discrepancy worth flagging: some bio aggregators (including celebswiki.info) list her at 5’9″ (175 cm). No primary source — no interview, red-carpet measurement, or agency listing — supports the taller figure, and photos alongside her 5’10” sister Kendall consistently show Kylie several inches shorter. We publish 5’6″ as the mainstream consensus and note the outlier rather than picking a side blindly. Either way, her height has never been the story — her business was built on lips, not runways.

Early Life: Sierra Canyon, Cheer, and a Homeschool Diploma

Kylie Kristen Jenner was born August 10, 1997, in Los Angeles to Kris Jenner, television personality and businesswoman, and Caitlyn Jenner, the 1976 Olympic decathlon champion (then known as Bruce Jenner). She is the youngest of the two daughters they had together; her full sister is Kendall Jenner, born November 3, 1995. From her parents’ other marriages she has eight older half-siblings, including Kourtney, Kim, Khloé, and Rob Kardashian on Kris’s side and Burt, Brandon, Brody, and Cassandra on Caitlyn’s side.

She attended Sierra Canyon School, where she was on the cheerleading team, before switching to homeschooling in 2012 as filming and modeling work consumed her schedule. She graduated with a high school diploma in July 2015 from Laurel Springs School in Ojai, California — one month before her 18th birthday, and four months before she launched Kylie Lip Kits. The timing is easy to miss: she was still finishing high school while building a company that would make her a billionaire on paper four years later.

Kylie Jenner Net Worth in 2026

Kylie Jenner’s net worth in 2026 is estimated at $670–700 million. Forbes puts her around $670 million; Celebrity Net Worth holds at $700 million. The spread comes down to how analysts value her retained ~44% stake in Kylie Cosmetics — a private company whose revenue hasn’t been independently disclosed since the 2019 Coty deal. Beyond cosmetics, her portfolio includes Kylie Skin (launched 2019), the Khy clothing brand (launched November 2023), Sprinter canned cocktails (2024), seven-figure-per-post Instagram income (~391 million followers), and her Hulu salary from The Kardashians. Her Holmby Hills estate, bought for $36.5 million in April 2020, anchors a California real-estate portfolio in the tens of millions.

What 29 Looks Like: The “Clock Is Ticking” Era

Two weeks after her birthday, Kylie appeared on the cover of Who What Wear‘s August 27, 2026 issue — rocking a frosty-blue bob that revived her 2014 “King Kylie” hair — and gave the quote that defined her year. “I think there’s something that happens when you’re turning 29, I’ll be 30 next year, and you almost feel like the clock is ticking, even though you’re still so young,” she said. She described planning a “personal refresh”: choosing a few things a year, getting out of her comfort zone, doing brave things without regrets — citing Kim Kardashian as her model for chasing dreams that scare her.

That refresh has visible edges. She appeared in Charli XCX’s A24 mockumentary The Moment (released January 30, 2026), a satire of modern musical fame — her first scripted film role, one she said she lobbied for herself on a flight with the director. She told Who What Wear she’d since turned down two scripts but had read a pilot she called “the best I’ve felt about something so far.” And Season 8 of The Kardashians premieres on Hulu on October 8, 2026 — four days from now — where, presumably, the rest of the 29th year will play out on camera. If her twenties were about building the fortune, her own framing suggests the last year of them is about deciding what the fortune was for.
