James Franco wants to make one thing clear—he has never slept with Lindsay Lohan. Rumors started swirling when an alleged copy of the list containing Lohan's 36 lovers was discovered at her Beverly Hills Hotel in January. After insisting multiple times that he had no right to be on the list, Franco, 35, again defended his innocence on The Howard Stern Show on Wednesday, April 30.

"I will swear on anything you ask that I have never had sex with Lindsay Lohan," Franco promised the prying host. "I bet if you brought her in here and you asked her face, 'Did you have sex with James?' she would say 'Yes.' I think she's that…"

"Delusional?" Stern offered.

"Or doesn't remember?" Franco mused. "Alright, we maybe kissed. It was lame. I can't believe she put me on that private list! She's so delusional!"

The Of Mice and Men star said that when they kissed he was "in awe" of Lohan's higher celebrity status, but that he quickly felt bad about it, considering "she was young."

Later in the pair's history, they were living in the same hotel. Franco recalled one night where he woke up at 3 a.m. to find Lohan, now 27, standing over him after letting herself into his apartment, but instead of taking advantage of the situation, he assured Stern that he remained a gentleman. 

"It sounds so nerdy, but I read her a story," he confessed. "I will swear on my mother's life that I never had sex with her."
