“Rockstar 101” is the fourth single off Rihanna’s latest album Rated R.  In the music video we find Rihanna, well, living the life of a (sexy) rockstar.  At one point she even dresses up as Slash (who lends guitar licks to the track), top hat and all.  Also, look out for drummer Travis Barker.  The video was directed by Melina Matsoukas who also headed the videos for “Hard” and “Rude Boy.”  The visuals, per usual, are slick.
