Rihanna is not one to mess with especially when it comes to Twitter. Today, actress Amanda Bynes bashed the “Pour It Up” singer over the social network. This morning Amanda tweeted, “Chris Brown beat you because your not pretty enough” and “No one wants to be your lover so you call everyone and their mom that I almost named my new dog Rihanna”. Amanda’s cheek piercings must be on too tight or something. Rihanna shot back with, “See what happens when they cancel intervention?”, adding more fuel to Amanda’s already blazing fire. “Unlike ur ugly faced self i dont do drugs. U need the intervention dog! I met ur ugly face in person! U aren’t pretty and u know it!”. While media’s saying that Amanda bashed Rihanna for no reason, there’s obviously a reason that we don’t know of! Honestly, Amanda! You screwed up for publicly bashing the girl. Get out of the public eye and get yourself together! Amanda showed up to court a couple days ago for throwing a bong out of her New York apartment window looking a disoriented mess. Just one of the girl’s many screw ups! If this girl actual decides to get herself together, get her Nicki Minaj’s hair stylist while she’s gone!
