Amanda Bynes BLASTS Rihanna on Twitter — ‘Chris Brown Beat You Because You’re Not Pretty Enough’

Amanda Bynes
just inexplicably railed on Rihanna on Twitter, saying Chris Brown beat her because she”s ugly … but RiRi got the last word and it was AWESOME.

Bynes tweeted — and quickly deleted — “@rihanna Chris Brown beat you because you”re not pretty enough.”

She followed that up with another insult — about wanting to name her dog Rihanna. It”s unclear what set her off.

RiRi clearly got wind of the deleted tweets, because she just posted the BEST COMEBACK EVER:

Ya see what happens when they cancel Intervention

Don”t mess with RiRi.
