"I never did a sex tape," Doherty, 39, tells Parade. "I never didn't wear panties and flash a camera ... When I made a mistake, I would admit to it. These girls don't seem to see their own mistakes, much less learn from them."
The actress, who says she's "shed" her past negative reputation because today she's "kind of a different person," believes it may be more challenging for Lohan to overcome her struggles.
