Sophia Bush has made it clear not to mess with her or her friends.
The star recently lashed out against social media users who were hating on her friend and former co-star, Hilarie Burton, after Burton said she would not attend the annual "One Tree Hill" EyeCon convention.
On Tuesday, Burton took to Twitter to share the news that she would not be attending the upcoming EyeCon event or any of the company's events in the future.
Burton wrote, "I'm sorry Mary. I will not be attending any EyeCon events. Ever," Burton wrote to a fan. "I personally feel exploited by their ‘girl power' angle, which exists at the expense of some of us who went through a difficult time on that show. They're using our sisterhood as a sales gimmick. No thanks."
After sharing her sentiments, the "One Tree Hill" actress received backlash from angry fans who responded to her statement defending the EyeCon women's empowerment theme.
One user wrote, "@HilarieBurton ‘Girl Power Angle' WOW I'm part of the Eyecon company made up of mostly women and I'm on that ME TOO list! You know nothing about US or the women who help me get out of bed ever day so I can find myself again."
Another accused Burton of calling the "Girl Power" theme an "angle" and said, "'Girl Power' isn't an angle, it's a way of life. I am proud to work for a company that is made up of mostly women. I am proud to be part of a company that puts smiles on people's faces. I am proud to be part of @EyeCon3000."
But it didn't take long for Bush to interject and defend her friend. The actress shut down the haters and said in a tweet, "Hilarie Burton is my sister. Don't f--- with her. Period."
Along with the tweet, Bush shared images of a lenghty message where she defended Burton's views.
In the message Bush elaborated on why she, Burton and other females in the industry feel as if they are being "exploited." Bush wrote, "Want to know why Hil said she feels exploited by this 'empowerment' con? Well add my name to that hat. Because so do I. We told our stories. As a united front. We refused to let it get tabloidy and gross. And then suddenly a convention publicly announced that they want to empower women? Now, that would have been FINE – lovely, even – IF THEY HAD SPOKEN TO US ABOUT THIS. Had they called our reps and said, 'as fellow victims in our own individual ways, we want to make the next con all about women, and raise money for women's charities.' They did not. Let me repeat. They. Did. NOT."
Burton later responded to Bush's message by sharing a photo of the two from "One Tree Hill" with the caption, "For life. X"
This is not the first time Burton has made controversial headlines. Back in October, the actress came out and accused Ben Affleck of groping her while on the set of MTV's TRL in 2003.
After facing backlash on social media, Affleck later issued an apology to Burton via Twitter.
A month after Burton spoke out about Affleck, it was reported that the "One Tree Hill" showrunner, Mark Schwahn, was accused of sexual harassment by 18 members of the show's cast and crew. Since the news of Schwahn's inappropriate behavior broke, the executive was fired from his current post as showrunner for E!'s scripted series, "The Royals."
