James Franco says not only has he never had sex with Lindsay Lohan, but she actually broke into his hotel room once in an effort to seduce the poor fella.

The actor was having an interview with Howard Stern this week when asked about that whole Lindsay sex list thing. According to James, Lindsay has more than just a few brain cells missing.

"I will swear on anything that you ask that I have never had sex with Lindsay Lohan!" he said. "Here's the problem: I bet you if we brought her in here and you asked her to her face ‘Did you have sex with James?' she'd say yes. I think she's that..."

"Delusional?" Stern offered, "Or doesn't remember," James responded, admitting they kissed once, when he was making Spider-Man.

"When we made out it was so long ago," he explained. "I was like a nice guy. I can't believe she put me on that private list. She's so delusional! I don't know what to say other than we were at this hotel during a very dark period of her history and I think she liked, it seemed pretty damn clear that she liked me."

And here's the best part - desperate LiLo even broke into his hotel room to get to him.

"She even broke into my room one time, because she was so at home there I guess they just gave her a key," he added. "I was on the couch and I opened my eyes and there's Lindsay in my room at 3 a.m."

Yikes.
