Amanda Bynes slammed Rihanna via Twitter on Monday, by calling the singer "ugly" and saying that her former boyfriend, Chris Brown, was justified to beat her up.
Bynes outrageously said that the songbird deserved to be a target of domestic violence, the New York Post reported.
"Chris Brown beat you because you're not pretty enough," Bynes tweeted.
"No one wants to be your lover so you call everyone and their mother that I almost named my new dog Rihanna," she wrote.
Later, Rihanna briefly responded back by saying: "Ya see what happens when they cancel Intervention?"
