Ever find yourself scrolling through Twitch, seeing a familiar strawberry-themed avatar, and wondering how someone has stayed at the top of the mountain for so long? I've been there. You see her cracking jokes in Fortnite or trying to figure out Age of Mythology and it hits you: she’s been doing this forever. Naturally, the question pops up—how old is Loserfruit, really?
Kathleen Belsten, the woman behind the "Lufu" moniker, isn't some teenager who got lucky during a summer break. She’s a veteran.
Kathleen was born on February 22, 1993. Since we’re currently in January 2026, she is 32 years old. She’ll be hitting the big 33 in just about a month. It’s wild to think she’s been a staple of the internet since 2013. That is over a decade of being "on." Most people burn out in three years.
The Timeline of Kathleen Belsten
She grew up in Melbourne, Australia. Back then, gaming wasn't "cool" like it is now. She actually hid her gaming hobby while she was in school. Imagine being one of the world's most famous gamers and having to keep your League of Legends addiction a secret from the kids in homeroom.
By the time she started her YouTube channel in 2013, she was roughly 20 years old. She wasn't an overnight success. She ground it out with satirical League videos and later Overwatch. But the real explosion happened when Fortnite took over the world in 2017. By then, she was 24, which is basically "prime time" for a creator to have the maturity to handle a massive audience but the energy to stream for 10 hours straight.
It wasn't just about playing games, though. She became a founder of the Click House, that legendary (and now disbanded) Aussie creator group. She was in the trenches with LazarBeam and Muselk, doing the most ridiculous IRL challenges you can imagine.
Why Knowing How Old Is Loserfruit Matters for Fans
Age in the streaming world is a funny thing. There’s this weird myth that once you hit 30, you’re supposed to retire and buy a farm. Kathleen is actively proving that’s nonsense.
Look at her recent stats from early 2026. She’s still pulling in thousands of viewers. She’s still experimenting. Just a few days ago, she was live-streaming a 100% completion run of GTA 5 while waiting for GTA 6. She’s also been grinding Age of Mythology, trying to hit a rank 1000. That doesn't sound like someone who’s slowing down because they’re in their thirties.
Major Career Milestones by Age
- 20 Years Old (2013): Launched the Loserfruit channel.
- 24 Years Old (2017): Pivoted to Fortnite, which changed everything.
- 27 Years Old (2020): Became the second person ever (after Ninja) to get her own Fortnite Icon Series skin. That was a massive "I've made it" moment.
- 32 Years Old (2025-2026): Still a powerhouse, hosting tournaments like the "IRL Fortnite Tournament" and participating in high-stakes FNCS Pro-Am events.
More Than Just a Number
Honestly, her age is probably her superpower at this point. She has a level of "internet wisdom" that younger creators lack. Back in 2021, she went through a bit of a crisis where she openly talked about losing her love for making content. She was 28 then. A lot of people thought that was the end.
Instead of quitting, she pivoted. She started doing the All In podcast. She leaned into vlogging on her Lufu channel. She signed massive deals with brands like e.l.f. Cosmetics and Gymshark. She realized she didn't just have to be "the girl who plays Fortnite." She could be a brand.
The e.l.f. partnership was actually a huge deal for the industry. They launched "e.l.f. U" (University) to support female gamers. She used her platform to talk about how male-dominated the space is. That's the kind of stuff you do when you’ve grown up in the industry and seen the ugly side of it.
What is Loserfruit doing in 2026?
She’s currently ranked among the top variety streamers on Twitch. Her schedule is still pretty packed, often streaming five or six days a week. You’ll find her in the "Just Chatting" section a lot more these days, just yapping with her community.
People always ask about her net worth too. While those "net worth" websites are usually guessing, her social media earnings are public enough to show she’s doing incredibly well. Between YouTube ad rev, Twitch subs, and those long-term brand deals, she’s easily one of the most successful Australian creators ever.
It’s also worth noting her philanthropic side. She’s raised hundreds of thousands of dollars for charity, including a massive 36-hour stream for the Australian bushfire relief.
Final Insights on Kathleen’s Journey
So, if you were wondering how old is Loserfruit, you have your answer. She’s 32, turning 33 in February. But more importantly, she’s a survivor in an industry that usually eats people alive.

If you want to keep up with her latest moves, the best thing to do is catch a live stream on Twitch during her "degen weeks" where she plays until the sun comes up. You can also check out her main YouTube channel for the highly edited gaming highlights or her second channel, Lufu, if you want to see the "real" Kathleen behind the monitor.
The most actionable thing you can do as a fan is to support the longevity of creators like her. The internet is fickle, but Kathleen has proven that you can grow up, change your interests, and still keep a loyal community.
If you’re looking to start your own streaming career, take a page out of her book: don't be afraid to hide your hobbies until you're ready to turn them into an empire, and never be afraid to tell your audience when you’re feeling burnt out. Authenticity is what keeps people watching for over a decade.
