'She's All That' star Rachael Leigh Cook is back in the spotlight and she's fighting the good fight against an unlikely enemy: Photoshop.

The actress directed her argument to the audience at the Healthy Media for Youth Summit in Washington, D.C., claiming that doctored images of celebrities had a potentially negative effect on young people's self-esteem.

"Nothing that you see is real, even if you look at what looks like a candid photo of someone, anything can be done. It is false advertising," she told the crowd.

Despite her healthy attitude toward media pressure, CBS News reports that the actress admitted to struggling with her own body-image issues following weight gain as a teen. "You're looking for a sense of control, and when you're in a really transitional phase in your teenage years, I think it's a pretty normal reaction to develop food issues," she explained.
