Rapper Gucci Mane slept through his sex scene in new movie Spring Breakers because he was so high on drugs.

The rap star plays a criminal named Archie in Harmony Korine's upcoming film, and the director reveals Mane was so exhausted and high during the early morning shoot, the 33 year old couldn't stay awake.

Korine tells New York Magazine, "In his entourage, everybody smokes weed from the beginning of the day to the end. So we're inside this house in St. Petersburg (Florida), and the f**king weed smoke was so insane and Gucci was basically catatonic. I was like, 'Gucci, you've got to have sex with this chick now!'

"So we're shooting the sequence, and as he is getting f**ked, I start to hear snores. He had literally passed out! And she was riding his d**k the whole time. I'd never in my life filmed a sex scene where the dude was sleeping... and she was on top of him for a good 45 minutes.

"At the end, he woke up and was like, 'I feel real nice. I feel like Mozart's on my d**k.' And that was it, and he went back to sleep."

And Korine insists he did everything he could to cast a love interest the rapper, real name Radric Davis, would find desirable: "They (his entourage) sent me a clip of this girl walking across the room with three or four Coke cans on her a**, and we cast her, based on that video."
