Amanda Bynes is having a rough week, between her arrest, some bong-throwing, and accusations of being sexually harassed by the NYPD. But that's no reason to take it all out on Rihanna.
Bynes tweeted the below at Rihanna, then quickly deleted it. TMZ thankfully, was ever-vigilant: "Chris brown beat you because you're not pretty enough," and then, "no one wants to be your lover so you call everyone and their mother that I almost named my dog Rihanna."
And then Rihanna decided to engage with Bynes, and pretty beautifully shot her down:
Which threw Bynes into a rage, where she tweeted (and quickly deleted), "@rihanna unlike ur fugly faced self I don't do drugs! U need the intervention dog! I met ur ugly face in person! U aren't pretty u know it!"
