Sydney Sweeney's Rumored OF Arc In 'Euphoria' Ignites Fiery Reaction From Sophie Rain

In a twist no one saw coming, the internet is buzzing over reports that "Euphoria" may introduce an OnlyFans storyline for Cassie Howard, and real-life creator Sophie Rain isn't letting the rumor slide quietly.

After a Brazilian outlet claimed Sydney Sweeney's character will launch an OnlyFans in Season 3, Rain fired off a spicy response that quickly went viral.

Now, she's doubling down, offering commentary that is equal parts playful shade and professional reality check.

Rain didn't hold back when asked how she felt about Sweeney stepping, even fictionally, into her world.

Speaking exclusively to The Blast, she acknowledged the attention but insisted she wasn't shaken.

"She'd be cute competition," Rain said. "But let's be real, I've been doing this in real life while she's pretending for the camera."

The spark began when Culture Crave cited a report from Omelete claiming Sweeney's "Euphoria" character, Cassie Howard, would start an OnlyFans account in the show's next season.

Rain reacted instantly on X with the now-viral quip: "Sounds like I finally have some good competition now."

Tens of thousands of likes later, the conversation exploded.

While the rumor has stirred excitement among "Euphoria" fans, Rain is taking a more skeptical approach.

"Sydney's gorgeous, no doubt. But being hot on HBO is different than holding attention for real subscribers day after day," she said. "She gets a script. I get requests."

Rain openly questioned whether the show would portray the actual grind behind the platform.

"Are they going to show what it actually takes to build a following, or is this going to be some glamorized, filtered fantasy version?" she asked. "Because if she's not answering DMs at 2 a.m. or fighting off weird comments, it's not a real OF experience."

With a laugh, she added, "They should've called me. I could've given them notes."

Reports also suggest the storyline may involve Nate discovering Cassie's account, adding another dramatic layer to the third season's shift.

If Sydney Sweeney's character does eventually enter the OnlyFans universe, Rain has one final message for her fictional competitor.

She stated, "If she's joining OF, tell her welcome to the hustle. But she better bring more than good lighting and heartbreak. This is grown-woman territory."

Despite the shade, Rain says she's excited to watch how Season 3 unfolds.

"Of course I'm tuning in," she admitted. "I need to see what kind of competition I'm dealing with."

With "Euphoria" expected to return in 2026, fans now have a whole new rivalry to look forward to, one that blends HBO drama with real-world digital fire.

The drama surrounding Sweeney's "Euphoria" character joining OnlyFans comes amid the recent news about her partnership with American Eagle, which became one of the most financially explosive celebrity collaborations in recent memory.

What began as controversy surrounding her July campaign ultimately transformed into a major win for the retail giant, driving its stock up by an impressive 10%.

The move added roughly $400 million in market value and sent web traffic surging by more than 100% as limited-edition pieces sold out in under 48 hours.

According to Brookerchooser, who analyzed celebrity-driven market spikes in an email to The Blast, Sweeney's collaboration outperformed major names across entertainment and sports.

While star-driven boosts aren't new — Beyoncé lifted Verizon shares by 2.5% with her viral Super Bowl commercial, and Kim Kardashian helped Nike's stock climb 6% when NikeSKIMS launched in September — none came close to matching Sweeney's dramatic impact.

Kardashian's second NikeSKIMS drop on November 10, 2025, expanded materials and accessories, but even that momentum didn't rival Sweeney's unexpected retail takeover.

The numbers place Sydney Sweeney ahead of some of the world's most influential figures.

Beyoncé's widely discussed Verizon ad, where she attempted to "break" the network while teasing new music, delivered a solid but comparatively modest 2.5% spike in shares.

Kim Kardashian's collaboration with Nike drove a 6% rise, notable, yet still far from Sweeney's 10% jump.

Even major athletes couldn't top the surge. French football superstar Kylian Mbappé boosted Dior's stock by 9% after his appointment as global ambassador in 2021, narrowly trailing Sweeney's performance.

NFL player Travis Kelce contributed to a 4.6% rise in American Eagle shares with his AE x Tru Kolors streetwear line earlier this year, but again, the impact didn't reach Sweeney's historic level.

What started as backlash against Sweeney's campaign has unexpectedly evolved into a market case study on celebrity influence and a clear sign that her star power carries rare financial weight.
