In Rihanna’s hot new vid, “Rockstar 101″, she does a pretty mean Slash impression. Who knew RiRi would make a hot old ax man? Or as “flattered” Slash himself told MTV, “The video is way better with her being me than with me being me … it brings an element of sexuality to it that I probably wouldn’t have been capable of.” I dunno, Slash, I’ve never seen you in a onesie!

Check out some famous rocker dudes and celeb ladies who accidentally share hilariously close haircuts.
