This was what he said:
"I was just hanging out [after a photo shoot], and one of the models took an iPhone picture, which circulated the planet before the shoot was even over... I took one of the photographer's lenses and held it up on my [phone] and said "imagine this one day". Then I said: "I'm going to do this"."
Sounds pretty awesome. Whats your say on this, feel free to comment.
