Someone isn't telling the truth.

Rose McGowan put Ben Affleck on blast after the actor released a statement claiming he was unaware of Harvey Weinstein's sexual misconduct with women, claiming that she personally told the Argo star she was sexually harassed by the studio exec when they were working on a movie together. The A-list star told her he had warned Weinstein to knock it off, and she used his direct quote in her tweet calling him out.

"Ben Affleck f*ck off. GODDAMNIT! I TOLD HIM TO STOP DOING THAT’ you said that to my face. The press conf I was made to go to after assault. You lie," she tweeted.

The Oscar winner insists he was in the dark about Weinstein's predatory ways.

"I am saddened and angry that a man who I worked with used his position of power to intimidate, sexually harass and manipulate many women over decades. The additional allegations of assault that I read this morning made me sick," he wrote on Facebook.

"This is completely unacceptable, and I find myself asking what I can do to make sure this doesn’t happen to others. We need to do better at protecting our sisters, friends, co-workers and daughters. We must support those who come forward, condemn this type of behavior when we see it and help ensure there are more women in positions of power," he added.

The Hollywood heartthrob might not be so innocent himself, either! Hilarie Burton revealed that he grabbed her boobs during an appearance on TRL in the early 2000s, after a Twitter fan brought up the incident. "He also grabbed Hilarie Burton's breasts on TRL once. Everyone forgot though," the fan wrote. "I didn't forget. Seriously, thank you for that. I was a kid," she responded, along with a video of the moment.

Everyone better watch out, Rose the truth teller is comin' for ya!
