A joke about walking into the gym did more for her than any dance trend. The video passed seven million views, and it told her exactly what her audience wanted.

Kayla Manousselis is 22 years old, an American content creator with more than 1.2 million TikTok followers. She has been posting since 2018, and her account has grown from lip syncs into fitness and beauty content.

Who Is Kayla Manousselis?

She is an American social media personality and model who built an audience on TikTok, posting as @kaylamanouss. Her content mixes trending dances, lip syncs, modelling and fitness videos.

She is one of a generation of creators who started as teenagers during TikTok’s first wave and turned it into a working career. The account is the business, and brand partnerships are how it earns.

What she does not have is a crossover moment. There is no television appearance, no music release and no public controversy, which is why the written record about her is so much thinner than her follower count suggests.

Her Age and Birthday

She was born on March 28, 2004, which makes her 22 years old. Her birthday falls under Aries, and she turned 22 in March 2026.

Plenty of profiles still list her as 20 or 21. Those were written in 2024 and 2025 and never updated, which is worth knowing before trusting anything else on them.

She was 14 when she posted her first TikTok. Most of her teenage years happened in front of an audience that grew into the hundreds of thousands, which is a fairly modern kind of adolescence.

Where Is She From?

She is American, and that is as specific as the public record gets. No city or home state has ever been confirmed, and every profile simply lists the United States.

Reports place her at San Diego State University after finishing high school, and suggest she now splits her time between San Diego and Chicago. Neither detail has been confirmed by her.

The vagueness is partly deliberate. She has kept her background and family almost entirely out of her content, which is unusual for a creator in the lifestyle space.

Most creators in fitness and beauty lean on personal story, since audiences respond to it. She has built the account on routine and personality instead, and the result is a large following attached to very little biography.

Kayla Manousselis Biography

How She Started on TikTok

Her first TikTok went up in 2018, set to music by rapper Mike Stud. She was 14, and the platform itself was barely a year old under that name.

The early content was what everyone was making then, which meant trending dances and lip syncs. That was the entry point for most creators of her age group, and it is the reason so many of them share a similar origin story.

What separated her came later, when she moved toward fitness and beauty. That shift gave her a clearer identity than dance content ever could, since trends change weekly and a niche does not.

The timing helped as well. Fitness content on TikTok grew sharply from 2020 onward, and creators who moved early into gym and routine videos found an audience that keeps returning rather than scrolling past.

The Video That Changed Things

Her most-viewed TikTok is a joke about walking into the gym, and it has passed seven million views. For an account her size, that is a video that reached far beyond her own followers.

Gym humour works because it is universal and self-deprecating. It also sat perfectly at the intersection of the two things her account was already about, which is fitness and personality.

Seven million views is also a useful marker of reach. An account with 1.2 million followers producing a video at that level has broken out of its own audience, which is what brand partners look for when deciding who to work with.

That clip did more than add followers. It confirmed the direction of the account, and the fitness and beauty content that followed is what she is now known for.

What Kind of Content She Makes

Her videos fall into a few consistent categories. There are fitness posts, covering workouts and gym routines, beauty content on products and routines, modelling and fashion videos, and the dance and lip sync material she started with.

The mix is deliberate. Fitness and beauty attract brand partnerships, while dances and trends keep the account visible in the algorithm, and the two support each other.

Her audience skews young, mostly teenagers and people in their early twenties. That is the demographic advertisers in beauty and activewear pay most to reach, which explains the partnerships she has attracted.

Brand Work and BOUTINE Los Angeles

The brand most associated with her is BOUTINE Los Angeles, a clothing label she has promoted across her platforms. Partnerships like that are the main revenue model for creators at her follower level.

Influencer marketing works on engagement rather than raw audience size. A creator with just over a million followers in a defined niche is often more valuable to an advertiser than a larger general account, because the audience is predictable.

Activewear and swimwear labels in particular rely on this model. They need creators whose followers already care about fitness and clothing, and a dedicated account converts better than a celebrity endorsement at ten times the price.

She has not announced a brand of her own. For now the business is built on other people’s products rather than her own line, which is a different model from creators who move into launching labels.

Her Boyfriend, Matt Karis

She has been in a relationship with Matt Karis for several years. He is a fitness enthusiast, and he appears regularly in her videos and posts.

The two of them making fitness content together is part of the appeal for her audience. Couples content performs well on TikTok, and in their case it overlaps naturally with what she already posts.

Beyond that, she keeps the relationship fairly low key. There are no engagement announcements and no detailed interviews about it, just regular appearances in each other’s content.

That restraint is consistent with how she handles everything personal. The relationship is visible without being the subject, which is a harder balance to strike than it sounds on a platform built for oversharing.

Her Family

She keeps her family almost entirely private. She has referred warmly to her mother on social media, and she has a dog that appears occasionally in her videos.

Names and details of her parents and siblings circulate on some profiles, but they come from a single source with nothing to corroborate them. Given she has chosen not to put her family online, repeating unverified names about them is not something worth doing.

Height and Appearance

Her height is reported at around 5 feet 4 inches, with weight figures circulating alongside it. Neither has been confirmed by her, and both appear to have spread from one early profile.

Measurements published about creators are usually estimates taken from photographs. They should be read that way rather than as facts.

Her Net Worth

No verified net worth figure exists. Published estimates range from around $400,000 to $600,000, and neither number has a source attached to it. The gap between the two is itself a sign of how little anyone knows.

What can be described is how creators at her level earn. Income comes from brand partnerships, sponsored posts, platform creator funds, affiliate links and occasional modelling work, with partnerships doing most of the work.

A precise figure for a 22-year-old independent creator is not something public information can produce. She has never discussed her earnings, and nothing about her finances is on record.

Follower count is a poor proxy for income in any case. Engagement rate, niche and the quality of brand relationships matter more, and none of those is visible from outside.

Where to Follow Her

Her main platform is TikTok, where she posts as @kaylamanouss. That account is where the audience is and where almost all of her content lands first.

Where to Find Her

Instagram@kaylamanousselis, reported
Snapchat@kaylamanouss17, reported
X@manousselis, reported
Only the TikTok handle is consistently confirmed across sources. The others appear on secondary profiles and are worth checking before following.

Her search profile sits in the middle tier of creators her age. She is well known enough to draw steady interest, without the mainstream recognition that comes with television or music.

What Is Actually Confirmed About Her

The verified record is short. That is worth stating plainly rather than padding around, because the gap between what is known and what is published about her is wide.

  • She was born on March 28, 2004, making her 22
  • She is American, with no city publicly confirmed
  • She began posting on TikTok in 2018
  • Her account @kaylamanouss has more than 1.2 million followers
  • Her content covers dance, lip sync, fitness and beauty
  • She promotes BOUTINE Los Angeles
  • She is in a relationship with Matt Karis

Everything else, including her birthplace, university, height and net worth, rests on secondary profiles. None of it comes from her directly, and some of it has been repeated for years without anyone checking.

Creators and the Search Problem

Something worth noting about creators her age is how little of what is written about them is checked. Most profiles copy a single source, and once a number is wrong it stays wrong for years.

Jessie Murph is a good example from music, where almost the entire internet published the wrong height until her own lyric settled it. The pattern repeats across the creator economy, where an unverified figure gets copied until it looks official.

For readers, the practical takeaway is simple. Treat anything beyond a creator’s own posts as an estimate, particularly ages, measurements and money.

In her case the age is the one worth correcting. She turned 22 in March 2026, and a surprising number of pages still have her two years younger than she is.
