Yesterday, a Rihanna fan appeared to misunderstand a retweet from her idol and got just a little too defensive in her reply, throwing a series of rude Chris Brown-related insults at the model. As always, Rihanna wasn't one to sit back and just ignore rude tweets, and it all got a little bit ugly.
Bottom to top.
