Has Rihanna ever posted anything on Twitter or Instagram that wasn't at least a little bit controversial?

The singer posted an Instagram pic of pot on January 2, along with the message, "This nug look like a skull or am I just....?" Not exactly the most profound question ever, if you ask us.

Many fans were upset with Rihanna's pic. One person asked her, "Why r u teaching other girls who look up to you to do this?"

Not long after that, Rihanna wrote, "I don't really give a f**k." So much for encouraging constructive criticism.
