Seth Rogen was ''genuinely shocked'' to discover marijuana was illegal in California.

The Canadian-born actor was arrested for drug use when he first moved to Los Angeles because he had forgotten about the fact they had different legislation than he was used to.

He recalled: ''I was genuinely shocked at how illegal it was here. I actually got arrested when I first moved to LA - I was smoking a joint at the beach, like I did my entire childhood, and all of a sudden, it was, like, whoop whoop whoop! Handcuffed in the back of a police car.''

Despite his arrest, the 'Interview' star doesn't believe he has a criminal record.

Meanwhile, Seth, 32, has had a special preview of Kanye West's next album - after the rapper invited him in his limo van and forced him to listen and give his opinion on each track.

Recalling how the 'Yeezus' star approached him in a New York hotel shortly after he and friend James Franco spoofed the musician's 'Bound 2' video - in which Seth played the role of Kanye's topless wife Kim Kardashian West - the actor admitted the session lasted much longer than he was expecting.

He told Rolling Stone magazine: ''There's no lyrics, only beats. So he raps the whole album, and after each song, he stops it, like, 'So what do you think?' We were in the van for two hours!''
