The Anatomy of the Infamous Throuple Era (2017–2019)

The relationship between Mod Sun and Tana Mongeau was never a traditional two-person romance. It began as an open relationship, or a "throuple," with actress Bella Thorne. This dynamic, which lasted from 2017 to early 2019, became a lightning rod for media attention and a defining moment for the careers of all three individuals, establishing a precedent for public, non-monogamous celebrity relationships.

The trio frequently shared intimate and chaotic details of their lives on social media, blurring the lines between private life and public performance. The relationship was characterized by its intensity, its bohemian lifestyle, and the constant scrutiny of the public eye. Bella Thorne, who openly identified as pansexual, was initially dating Mod Sun when Tana entered the picture, creating the complex "Mod Sun triangle."

The official breakup of the throuple was messy and highly public. Bella Thorne announced her split from Mod Sun in April 2019, shortly after the dynamic with Tana had already dissolved. The immediate aftermath involved a significant amount of public feuding, with all parties exchanging accusations on platforms like Twitter. Bella Thorne, in particular, called out Tana Mongeau for breaking "girl code," though the specifics of the drama were often vague and fueled by raw emotion.

Tana Mongeau's Shocking 2025 Reflections and Mod Sun's Recent Drama

The most compelling, up-to-date information on the Mod Sun and Tana Mongeau saga comes from Tana's recent candid interviews and podcasts, where she has been reflecting on the "chaos that made her." Her current perspective, voiced in late 2025, provides a surprising and emotional counterpoint to the public's perception of the relationship as purely dramatic and toxic.

1. Mod Sun Was Her "Lifeline"

In a surprising twist on the narrative, Tana Mongeau has recently stated that she "wouldn't be alive" if it weren't for her ex-boyfriend, Mod Sun. This powerful statement suggests that despite the public drama and the non-traditional structure of their relationship, Mod Sun provided her with a crucial support system during a difficult period in her young adult life. This reframing challenges the long-held belief that the "throuple" era was solely destructive.

2. The Controversial "Victim" Narrative

While Tana has offered praise, other social media commentators have recently resurfaced old accusations against Mod Sun. Following his dramatic split from Avril Lavigne, discussions on platforms like Reddit suggest that Mod Sun has a pattern of playing the "victim" in high-profile breakups. The claim is that he allegedly lied about the details of his split with Bella Thorne and Tana Mongeau to garner public sympathy, a pattern critics suggest was repeated in the Avril Lavigne saga.

3. The Throuple as a Career Catalyst

The high-visibility nature of the open relationship was a significant career boost for Tana Mongeau, solidifying her "unhinged" internet persona. The constant stream of "storytime" videos and the sheer volume of media coverage helped her transition from a standard YouTuber to a major internet personality who could monetize her life's drama, eventually leading to her lucrative OnlyFans career and the launch of Tana's Angels.

4. The Bella Thorne Feud is Officially Over

While the initial breakup led to a public feud between Bella Thorne and Tana Mongeau, recent updates confirm that the two have made amends. They have been seen reuniting and discussing the past, effectively closing the chapter on the direct, interpersonal drama from the throuple era.

5. Mod Sun's Role as a Pop-Punk Mentor

Beyond the personal drama, Mod Sun's influence on Tana Mongeau was tied to the music scene. As a veteran of the Warped Tour and the pop-punk genre, he exposed Tana to a different corner of the entertainment world. This cross-pollination of the YouTube and Music industries was a key entity in the late 2010s celebrity landscape.

6. The Unconventional Love Story

Despite the chaos, the dynamic was a genuine, albeit unconventional, love story for a time. Tana has consistently defended the authenticity of her feelings, emphasizing that the open structure of the relationship was simply a reflection of the non-traditional lives they led as young, famous, and constantly scrutinized public figures. It was a relationship that defied traditional labels and expectations.

7. The Enduring Topical Authority

The "Mod Sun Tana Mongeau" entity continues to hold topical authority because it represents a pivotal moment in celebrity culture: the mainstreaming of non-monogamy, the blurring of reality and content, and the rise of the influencer as a major celebrity. Every time one of them enters a new relationship, the shadow of the throuple era resurfaces, proving the lasting impact of their shared history.

The Legacy of the Mod Sun Triangle

The relationship between Mod Sun and Tana Mongeau, filtered through the lens of Bella Thorne, is a case study in modern celebrity. It was a chaotic, intense, and deeply public affair that propelled both of their careers forward, albeit through controversy. While they are no longer together—and Mod Sun has moved through other high-profile relationships, including his engagement to Avril Lavigne—Tana's latest reflections in 2025 ensure that the "Mod Sun triangle" remains a hot topic. Her surprising admission that he was a vital "lifeline" offers a complex, emotional depth to what was once dismissed as pure internet spectacle, leaving fans to continuously re-evaluate the true nature of their unconventional bond.
