Whether you’re brand new to Fortnite or have been playing since the early days, you’ve almost certainly heard the name Loserfruit. But who is she, really? Known as one of the most influential female streamers in the Fortnite community, Loserfruit has become a global gaming figure.
This guide breaks down everything you need to know about her: where she started, how she grew her platform, and the milestones that turned her into one of Fortnite’s most recognized personalities.
Kathleen “Loserfruit” Belsten is an Australian content creator who has firmly cemented herself as a leading figure in online gaming. With a combined following of more than 8.6 million across YouTube and Twitch, she stands alongside major names like Pokimane and LilyPichu.
Loserfruit gained traction through her energetic Fortnite streams and YouTube content. Her impact eventually earned her a spot in Fortnite’s Icon Series, making her the sixth creator ever to receive an in-game cosmetic after Marshmello, Major Lazer, Ninja, Travis Scott and Astro Jack.
These days, her content goes far beyond Fortnite. She frequently covers gaming events, collaborates on community projects and streams a variety of titles including Overwatch 2, Borderlands 4 and Marvel Rivals. She’s also active in Twitch’s Just Chatting category, where she spends time interacting directly with her audience.
Loserfruit began her content journey back in March 2013, launching her Twitch and YouTube channels around the same time. Her early videos revolved around comedic League of Legends content, but over time she branched out, experimenting with Minecraft, Overwatch and eventually finding her stride with Fortnite in late 2017.
When she stepped away from League content, she explained that she no longer felt the same passion for the game and wanted to explore titles that brought her more joy and creative success. Fortnite was still fresh at the time, offering new creators a chance to stand out and she capitalised on it.
Her audience quickly accelerated. In 2017, she sat at about 430,000 Twitch followers. By June 2019, that number had climbed past one million and just a year later she surpassed two million, right around when Epic Games introduced her Icon skin.
Outside of streaming, Loserfruit has taken part in multiple major Fortnite events, including the Celebrity Pro-Am tournaments in 2018 and 2019, where she placed 10th and 17th. She later returned for the FNCS 2025 Pro-Am, finishing 18th. In 2021, she joined Team PWR as one of their featured Fortnite creators.
She has explained in multiple Q&A streams that she chose the name simply because it sounded funny, unique and a bit self-deprecating in a playful way. The word “Loser” was intentionally ironic, reflecting her tendency not to take herself too seriously. She paired it with “Fruit” because she liked the way it sounded and because it gave the name a quirky, memorable twist.
Kathleen (Loserfruit) publicly announced her engagement to her longtime partner Marcus in August 2025. The pair revealed the engagement in a Q&A-style YouTube video, sharing details about the proposal and their plans. The wedding later took place on 4 November 2025.
Although Loserfruit hasn’t publicly revealed her exact earnings, Daily Mail estimates her net worth to sit somewhere between 3-4 million dollars. This figure isn’t confirmed, especially given that she earns income from several different sources including Twitch, YouTube, brand deals and sponsorships.
