Sydney Sweeney cannot seem to catch a break as she faces an onslaught of negativity from the online community. The backlash directed at Sweeney is largely the result of her appearance in a controversial ad campaign.As a result of the growing online backlash against Sydney Sweeney, her latest film, Christy, has suffered poor box office performance.

In the most recent development in this evolving story, Christy Martin (boxer and subject of Sydney’s biopic turn) has vocalised her support for the actress.Martin took to Instagram and posted a picture of herself alongside Sweeney, accompanied by what seemed to be a truly heartfelt plea to quiet the attacks."I’ve always been a fighter. My life reflected that in every way and now I fight for others. The past few days I have seen some people attack my friend Sydney Sweeney."The caption continues,"Syd not only worked her ass off for this film, she worked her ass off for me. For my story. For so many others suffering in silence. So I want to be clear about who Syd is. She is my friend and ally!"Christy Martin is clearly making a conscious decision to stand up for Sydney Sweeney amidst the chaos. It remains to be seen how the situation will ultimately unfold.

Actress Ruby Rose provided the most recent example of this.Rose made her stance on Sydney Sweeney's participation in the film clear via a post on Threads on November 11,“The original Christy Martin script was incredible. Life changing. I was attached to play Cherry. Everyone had experience with the core material. Most of us were actually gay. It’s part of why I stayed in acting. Losing roles happens all the time."Rose went on to add,“For her PR to talk about it flopping and saying SS did it for the ‘people’. None of ‘the people’ want to see someone who hates them, parading around pretending to be us. You’re a cretin and you ruined the film. Period. Christy deserved better.”It remains to be seen how the situation will resolve itself.
