Actor James Franco has given Lindsay Lohan's lovers list validity by finally confessing he locked lips with the actress.

But he claims the troubled actress later broke into his hotel room.

Franco's name appeared on a list of men Lohan had scribbled while in rehab last year.

A photo of the scrap of paper was taken by one of the actress' acquaintances and was published by a US tabloid earlier this year.

The accuracy of the list was called into question when Franco insisted he had never been intimate with the Mean Girls star.

But he eventually owned up to his romantic encounter with the actress during an appearance on shock jock Howard Stern's satellite radio show, although he still maintains there was no sex involved.

"All right, we maybe kissed," he admitted.

"It was lame. When we made out it was so long ago.

"I was, like, a nice guy. The kiss is enough. It was also like, 'What the hell am I doing?' She was young."

Franco said was in the middle of shooting Spider-Man 2 when he and Lohan hooked up.

The actress would have been 17 at the time.

They had another bedroom encounter years later when Franco was staying at the same hotel as the actress while studying at UCLA (University of California, Los Angeles).

"We were at this hotel during a very dark period of her history and ... it seemed pretty damn clear that she liked me.

"She even broke into my room one time.

"I was on the couch and opened my eyes and there's Lindsay in my room at 3am!"
