James Franco Says Lindsay Lohan 'Stalked' Him

"She even broke into my room one time," the actor said.

May 1, 2014 — -- James Franco swears "on my mother's life" he never had sex with Lindsay Lohan.

The "Palo Alto" actor, 36, spoke with Howard Stern on Wednesday and said even though she put him on her alleged sex list that somehow went public, things never went that far with the actress.

"Alright, we maybe kissed," he said, but added that "it was lame."

Franco said the kiss happened around 2004 when he was doing "Spider-Man 2" and was in New York.

He added that at the time, Lohan, now 27, was just a teenager and he even asked himself "what the hell am I doing," saying the kiss was as far as he went back then.

Though he also told Stern she probably has a different recollection of the incident.

"She's so delusional!" Franco added. "I bet you if we brought her in here and you asked her to her face, 'Did you have sex with James?' She would say yes."

After that incident almost a decade ago, Franco said he was staying at Chateau Marmont and that she would basically stalk him.

"I'd come home late to the hotel and she'd come find me," he said. "She even broke into my room one time ... I opened my eyes and there's Lindsay in my room at 3 a.m."

He added, "Yeah, that's stalking."

Stern said that maybe her list was of people she was once in love with.

"Maybe that's why I'm on the list of her obsessions," Franco replied.

Efforts by ABC News to reach Lohan's rep were not immediately returned.
