Amanda Bynes has completely moved on from her Twitter feud with Rihanna. Now, the former Nickelodeon star has a new enemy: Chrissy Teigen.
The model got on Bynes’ bad side when she tweeted: “The fact that Amanda Bynes has any 'support' to retweet is really unsettling.”
Then she added her followers should “Support people with mental illness, yes. But don't condone/enable scary and poor behavior.”
Bynes, predictably, fired back only moments later. The 27-year-old troubled starlet posted a rant about Teigen, calling her an “old ugly model.”
“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!” Bynes wrote. “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!”
Bynes concluded by adding “I don't respect you! You're no beauty queen! I'm a beauty queen!”
After Bynes’ post, Teigen encouraged her fans to refrain from posting negative things about the actress.
“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 wrote.
“Nope. Not going to indulge. Wish the best for her, truly,” the former Sports Illustrated swimsuit model wrote.
Earlier this week Bynes reportedly had similar Twitter arguments with Rihanna and Courtney Love.
On Tuesday, Love wrote to Bynes: "pull it together dude."
The starlet responded by calling Love the "ugliest woman" she's ever seen, according to multiple reports, but then deleted the tweet.
Similarly, the actress denied posting a now deleted tweet about Rihanna that read: "Chris brown beat you because you're not pretty enough."
Bynes rose to fame starring in Nickelodeon's "All That" and has also starred in several films, including 2010's "Easy A." But she has been in the news more recently because of several scrapes with the law and bizarre public behavior.
Bynes was arrested Thursday night after building officials called police to complain she was rolling a joint and smoking pot in the lobby. The officers went to her apartment where they saw heavy smoke and a bong sitting on the kitchen counter. They said she tossed the bong out the window in front of them, prosecutors said Friday.
