Amanda Bynes Slams Chrissy Teigen On Twitter: 'You're Just An Ugly Model' & 'I Don't Respect You'

Chrissy Teigen is just the latest celebrity to endure the wrath of Amanda Bynes.

On Tuesday, Bynes lashed out at the Sports Illustrated model after she tweeted, "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."

That comment didn't sit well with the 27-year-old troubled actress who has not been shy about firing back at some of her most famous critics.

In an extended tweet, Bynes slammed Teigen by calling her an "old ugly model," completely disregarding the fact the two are the same age:

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! 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!

If Bynes' ongoing behavior weren't so alarming it would almost be amusing that calling someone "ugly" consistently appears to be the absolute worst insult the actress can come with. And to her credit, Teigen chose not to retaliate and instead tweeted:

"Nope. Not going to indulge. Wish the best for her, truly."

The 27-year-old model went on to ask her fans not to get involved in the situation either, writing, "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."

Teigen isn't the only celeb to back off when it came to defending herself against Bynes. Rocker Courtney Love was slammed by the actress after she tweeted at her to "pull it together." Bynes responded by calling Love the "ugliest woman" she's ever seen.

Surprisingly, despite the name calling, Love tweeted back with messages of support:

While Bynes has clearly gone off the rails, she still has a number of people rooting for her recovery. Actress Alyssa Milano responded to Love's tweet to extend her own offer to help Bynes in what ever way possible.
