If you are on Twitter regularly, then you would know that Amanda Bynes is, um, a little crazy controversial. The troubled actress took to her Twitter account over the weekend to slander Rihanna, which quickly backfired on her.

For some unknown reason, Bynes decided to write a nasty tweet at RiRi that read, "@rihanna you look so ugly tryin to be white. Chris Brown beat you because you're not pretty enough."

Then she added, "No one wants to be your lover so you call everyone and their mother that I almost named by new dog Rihanna."

The offensive tweets were quickly deleted but not before New York Daily News could capture them in a screen grab.


Ouch!

An irate Bynes replied, "@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!"

Bynes has been in the news lately for her outrageous behavior both in the digital and real worlds. Most recently, the 27-year-old actress was arrested for reportedly smoking pot in her apartment building's lobby. She denies the allegations. She also allegedly accosted a photographer, calling him "the ugly black man."
