A Parisian-born content creator transformed a YouTube channel into a media empire. Her journey from uploading fitness videos to hosting national television shows charts a new path to fame in France.
She launched her channel in 2017. By 2025, she reached over three million subscribers. This digital success opened doors previously guarded by traditional media gatekeepers.
Her professional identity, Juju Fitcats, represents more than a fitness brand. It signals a generation of creators who moved from bedrooms to broadcast networks. They did this without losing their authentic voice.
Her career centers on content creation and television presentation. It shows a calculated evolution, not accidental virality. Strategic collaborations and a genuine connection with her audience sustained her relevance for nearly a decade.
This story examines the strategic choices behind the subscriber count. It looks at how digital influence now builds credible, multi-platform careers in the modern French media landscape.
Early Life and Education of Justine Becattini
A scientific education and fifteen years of equestrian sports provided the unlikely foundation for what would become a fitness media brand. The early years shaped the discipline and authority that would define her approach.
Birth and Childhood in Paris
Born in Paris’s 13th arrondissement in 1995, she grew up in Limours, Essonne. This suburban commune south of Paris offered space for athletic pursuits while maintaining proximity to the capital. The balance between urban access and suburban stability created an ideal environment for development.
Educational Journey and Passion for Equestrian
Her educational path followed traditional French institutions—Michel Vignaud middle school and Jules Verne high school in Limours. Earning a scientific baccalaureate positioned her for university studies in biology and health sciences.
Fifteen years of equestrian sports instilled competitive drive and consistency. This athletic discipline translated directly into the rigor required for content creation. The combination created a unique foundation for the Juju Fitcats brand.
| Institution | Location | Focus Area | Years |
|---|---|---|---|
| Michel Vignaud Middle School | Limours, Essonne | General Education | 2006-2009 |
| Jules Verne High School | Limours, Essonne | Scientific Baccalaureate | 2009-2012 |
| University Studies | Paris Region | Biology & Sports Nutrition | 2012-2015 |
| Equestrian Training | Limours Area | Competitive Sports | 2000-2015 |
Studying sports nutrition bridged academic knowledge with practical wellness content. This educational credibility gave the Juju Fitcats brand authority that set it apart from typical fitness influencers.
The Rise to Fame: From YouTube to Mainstream Media
With a completed degree in hand, the creation of Juju Fitcats represented a deliberate career choice rather than a casual experiment. Justine Becattini entered the digital space with academic credibility and a clear vision.
Launching the Juju Fitcats Channel
The channel debuted on August 27, 2017. This timing capitalized on YouTube’s peak as the dominant platform for long-form fitness content.
The pseudonym combined a playful nickname with fitness branding. It created a memorable identity in the crowded wellness space. Her background in sports nutrition gave the content unique authority.
Milestones and Breakthrough Moments
A key moment came at the 2017 Miss InShape election. There, she met fellow creator Tibo InShape. This connection sparked both personal and professional collaboration.
Growth was steady rather than viral. By 2025, the channel reached three million subscribers. This showed sustained audience trust over eight years.
The foundation built during these early years enabled the television career that followed. The Juju Fitcats brand proved digital success could translate to mainstream media.
Career Highlights on Television and Social Media
Winning a high-stakes television competition demonstrated her on-camera presence could extend beyond scripted content. The victory on Les Traîtres season 2 in 2023 marked a pivotal moment for Juju Fitcats. It showed television producers she possessed strategic thinking and natural charisma.
Transition from YouTube to Television Stages
Her television career built steadily through diverse appearances. She competed on Fort Boyard multiple times and tested culinary skills on Objectif Top Chef. Each show introduced her to audiences outside the fitness community.
The progression followed a clear strategy. First, she proved herself as a contestant in various formats. Then networks trusted her with hosting responsibilities.
In late 2023, she replaced Pierre-Antoine Damecour as presenter on La France a un incroyable talent, ça continue. This represented a major network bet on her appeal. M6 clearly believed her YouTube audience would follow her to traditional television.
By 2025, Juju Fitcats hosted multiple M6 programs simultaneously. She presented Les Traîtres révélations, Living Santé, and 99 à battre with established host Éric Antoine. This multi-format presence showed serious network investment.
Her acting debut in Nouveau Jour as Déborah tested new creative territory. The role expanded her range beyond hosting into scripted performance. It completed a remarkable transition from digital creator to mainstream media figure.
Personal Life and Influencer Ventures
Her partnership with Tibo InShape created one of France’s most influential digital power couples. Their combined ventures extend beyond content creation into strategic business ownership.
Relationship with Tibo InShape and Milestones
Meeting at the 2017 Miss InShape election sparked both personal and professional collaboration. Their relationship evolved publicly over five years before the September 2022 engagement.
The May 2025 wedding represented a major milestone shared selectively with fans. Following marriage, she legally became Justine Delapart while maintaining the Juju Fitcats brand.
Key developments in their partnership include:
- Moving from Paris to the Basque Country, aligning with wellness-focused branding
- Owning ShapeYou as a business entity independent of platform algorithms
- Balancing television work at M6 with collaborative digital content
The “couple 2.0” concept reflects their digital-native approach. Professional collaboration and personal life intertwine seamlessly across platforms.
This balance demonstrates media sophistication. It gives audiences connection while protecting personal boundaries essential for lasting influence.

Her music, including tracks with Tibo InShape, blurred lines between content and entertainment. These releases were performances designed for engagement. Her role in Nouveau Jour tested her appeal in scripted drama.
Role as a Trendsetter and Social Media Icon

Notable Collaborations and Industry Recognitions
Working with established figures like Éric Antoine on 99 à battre integrated her into traditional entertainment circles. Consideration for Danse avec les stars signaled serious industry recognition.
Her career path proved digital creators could build credible, multi-faceted careers. Television networks now actively recruit from online talent pools, a shift she helped pioneer.
