The provocative singer took to her website to post several photos of her wild weekend at the Coachella music festival in California, where she partied with pals, including Katy Perry.

But one image, published on her Instagram page, appears to show Rihanna rolling a joint on the man's head using a brown piece of paper.

She captioned the photo, "Memories don't live like people do #coachella," and attracted more than 1,000 comments from both fans and critics.

The "We Found Love" star seemingly addressed the uproar when she subsequently tweeted, "I'm crazy, and I don't pretend to be anything else."
