Spring Breakers star James Franco has hit out at Lindsay Lohan for putting him on her recently leaked conquest list.

The 36-year-old actor has said that he doesn't understand why he was put on Lohan's private list.

Speaking on Howard Stern's on radio show, Franco said: "I will swear on anything that you ask that I have never had sex with Lindsay Lohan! Here's the problem: I bet you if we brought her in here and you asked her to her face 'Did you have sexy with James?' she'd say yes.

"I can't believe she put me on that private list. She's so delusional!"

However, Franco admitted to locking lips with the 27-year-old star, saying: "Alright, we maybe kissed...It was lame."

He added: "When we made out it was so long ago. I was like a nice guy."
