Last night troubled actress Amanda Bynes came for Rihanna with a series of below the belt Tweets...
Amanda, who has been completely spiraling out of control lately, Tweeted Rihanna that Chris Brown beat her ass because she's not cute enough and told RiRi she looks ugly trying to be white.
Rihanna took it easy on Amanda and instead of ripping her to shreds joked about Amanda's drug use.
