Amanda Bynes has sent out some uncomfortable tweets in her day, but she managed to top herself by going after the world's most notorious victim of domestic violence.

Last night the alleged bong-thrower sent out some incredibly nasty tweets aimed at Rihanna:

The tweets have since been taken down.

The victim-blaming is pretty disgusting in itself. But Bynes seems to be especially fixated on appearance these days. She called a paparazzo who invaded her space and kept yanking a scarf off of her head "the ugly black one." She complained that E!

She said that after seeing pictures of herself in court, she needs help in the wig department. She's talked about needing to lose 35 pounds.

Whatever is going on in her head, it came out ugly. But Rihanna got the last word in:



Ya see what happens when they cancel Intervention? — Rihanna (@rihanna) May 26, 2013
