I'm not quite sure what's so funny. He's using his celebrity status to jump-start his very own porn empire. He could potentially make millions off this (if done right).
It would be folly to remain in the music industry since record sales are getting lower each year. It makes more sense to branch out into other ventures (i.e.: having your own clothing line, perfume/cologne, acting, real estate, hotel business, motor oil, vitamin water, porno, etc.)
