Amanda Bynes Fires Back at Model Chrissy Teigen on Twitter

Actress slams the model who claimed Bynes had a "mental illness"

After mastering the art of selfie pictures, Amanda Bynes is continuing to test her talents at Twitter feuding.

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!"

She continued, "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."

Instead of adding fuel to the fire, Teigen tweeted, "Nope. Not going to indulge. Wish the best for her, truly," and begged her followers to do the same. "Don't, guys. Just don't...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."
