Kanye West treated Seth Rogen and his wife to a two-hour freestyle rendition of his album Yeezus before its release, following a chance meeting in a hotel lobby.

The Knocked Up star was about to retire to his room with wife Lauren Miller when West invited them to get in his limousine and enjoy a sneak preview of the record.

The Stronger hitmaker used a backing track and launched into a two-hour freestyle version of the record as the shocked couple looked on.

Rogen admitted that West's eager nature and willingness with his craft and showmanship changed the way he now makes his own movies.

He tells Rolling Stones magazine, "Me and my wife had gotten some dessert and were in the lobby getting plates to bring back to our room... And Kanye was like, 'What are you guys doing? Want to hear my new album?' So he takes us to this limo van and starts playing his album - except 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!

"Now I realise the next person he sees that he knows is getting pulled into that van. But I learned a lesson from it - which is that Kanye is seeking input at all times. Process-wise, it showed an openness and a fearlessness. We started screening our movies more and in rougher versions for our friends because of that."
