The real Christy Martin is coming to Sydney Sweeney's defense after Ruby Rose claimed Sweeney "ruined" a biopic about the boxing icon. "I've always been a fighter. My life reflected that in every way and now I fight for others," Martin, 57, wrote alongside a photo of her and Sweeney, 28, on the set of Christy posted to Instagram on Wednesday, November 12. "The past few days, I have seen some people attack my friend Sydney Sweeney. 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," Martin continued.
