Amanda Bynes launched into a spiteful rant on Twitter after swimwear beauty Chrissy Teigan called for people to "support" the troubled actress and criticised those encouraging her downfall.
"Support people with mental illness, yes. But don't condone/enable scary and poor behavior," the Mirror quoted the 27-year-old Sports Illustrated swimsuit model as writing on her Twitter account.
The tweet sent Bynes into a rage and she responded with her own post, saying that Teigan was "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!" she wrote.
"You look 45! You're not pretty so I'm not intimidated by you! I think you're jealous that you're just an ugly model whos career is uninspiring! I don't respect you! You're no beauty queen! I'm a beauty queen," she posted on her Twitter account.
Teigan didn't directly respond to the attack instead she told her Twitter followers, "nope. Not going to indulge. Wish the best for her, truly.
"I never ask anything of you guys but please. I don't need defending and please stop writing her. It's not funny, it's sad," she added.
