Lindsay Lohan's co-star in new movie The Canyons has slammed the actress' on-set behaviour, likening her to a "child lashing out".

Porn star James Deen claims Lohan infuriated her co-workers with her attitude and often refused to venture onto the set.

"There were days when she would scream and yell and cry and refuse to come out," Deen told Britain's The Sun tabloid.

"In porn I am used to working with professionals who are courteous to others. But Lindsay was like a child lashing out."

Deen also alleges Lohan became angry when director Paul Schrader asked her to take her shoes off for a scene.

"It was a simple request. I am a short guy and it looked ridiculous with her towering over me in seven-inch heels.

"But she refused. She was crying and screaming that she was the star of the film. In the end it was decided I would wear boots to make me taller and she finally calmed down."

However, Deen admits he feels for Lohan, who found fame as a child star.

"She is a product of the Hollywood system. She is so fragile you can't help but feel for her."
