Ruby Rose Slams Sydney Sweeney Over Casting Shake-Up

November 11, 2025: Ruby Rose has sparked controversy after publicly calling Sydney Sweeney a “cretin” following reports that she lost the lead role in the highly anticipated biopic about champion boxer Christy Martin. The outburst has ignited a wave of reactions online, with fans and industry insiders weighing in on the escalating tension between the two stars.

According to sources close to the project, Rose was originally attached to play Martin, the groundbreaking female boxer who shattered barriers in the male-dominated sport during the 1990s. However, the role was later given to Sweeney, whose career has soared thanks to Euphoria and Anyone But You.

Ruby Rose’s Fiery Response

In a now-viral social media post, Rose didn’t hold back her feelings about the recasting. “Imagine taking on a role you clearly don’t understand just for clout,” she wrote. “What a cretin.” The blunt remark quickly made headlines, with many speculating about the behind-the-scenes drama that led to Rose’s exit.

While Rose has not provided details about why she left the project, insiders claim creative disagreements and scheduling conflicts were contributing factors. Sweeney has not publicly responded to Rose’s comments, but her team reportedly considers the remarks “unprofessional and baseless.”

Sydney Sweeney’s Rising Career

Sweeney, who has built a reputation for her versatility and dedication to physically demanding roles, recently revealed that she underwent months of intense boxing training for the film. “I wanted to embody Christy’s strength, her resilience, and her fire,” she said in a recent interview.

The upcoming biopic, produced by Amazon MGM Studios, is expected to delve deep into Martin’s groundbreaking career and her personal struggles, including her fight for survival against domestic violence and her role in transforming women’s boxing.

Industry Reaction

Hollywood insiders have expressed disappointment in Rose’s public remarks, noting that casting changes are common in major productions. “It’s unfortunate when personal feelings spill over publicly,” one producer commented. “Both actresses are talented in their own right, and this kind of feud only distracts from the story being told.”

Despite the drama, anticipation for the Christy Martin biopic remains high, with fans eager to see how Sweeney brings the legendary fighter’s story to life on screen.
