"I had some friends over that I probably should have questioned a bit but I don't like to see the bad in people, I like to see the good, so I ignored it and then someone must have stolen it and that's a really personal thing, that's something I would never do to anyone," the 28-year-old said.
"…That's something that is uncomfortable to have to say to anyone, let alone for it to be posted everywhere," she added. "So it's not a joke, it wasn't funny, it was cruel. It's bad karma for whoever did it. It was sh---y."
The list of Lohan's alleged 36 partners included stars such as James Franco, Justin Timberlake, Orlando Bloom, Adam Levine, Heath Ledger, and Zac Efron. She later confirmed writing the list during Watch What Happens Live's Plead the Fifth on April 18.
"You know what? I'm going to get serious for a second," she said at the time. "That was actually my fifth step in AA at Betty Ford [Drug and Alcohol Abuse Treatment Center]. Someone, when I was moving during the OWN show, must have taken a photo of it."
Franco later denied that he ever slept with the Mean Girls alum in an interview with Los Angeles magazine. He also wrote a short story for Vice in which the narrator spends the night with a fictional celeb named "Lindsay" — but doesn't have sex with her.
Lohan's response? "If someone wants to do that for their own reasons, there's nothing to say, I'm not in their head. [However] I would never do that. I didn't read it," she told Daily Mail. "When I started working we didn't have Twitter, we didn't have any of this s--t, it's a different world now. We didn't have Instagram, we didn't have camera phones for God's sake. It's really different now."
