The actress, who has called out a number of celebs on the social media site recently, slammed model Chrissy Teigen after she wrote, "The fact that Amanda Bynes has any 'support' to retweet is really unsettling...Support people with mental illness, yes. But don't condone/enable scary and poor behavior."
Bynes tweeted, "Ur not a pretty model compared to me. I signed to Ford models @ age 13. I don't look up to u beauty wise. I'm far prettier than u! I'm offended that you're saying I have a mental illness when I show no sign of it, but thankfully not one man that wants me wants you and you are an old ugly model compared to me!"
It sadly looks like Amanda's downward spiral is getting lower everyday.
