Los Angeles, California - The Chrissy Teigen bullying saga continues.

On Monday, Teigen published a lengthy apology on Medium, responding to bullying accusations levied against her by Courtney Stodden and others.

"There is simply no excuse for my past horrible tweets. My targets didn’t deserve them. No one does," she wrote in the essay, while asking for "patience and tolerance."

But just five hours later, designer Michael Costello came forward in an Instagram post accusing the model of bullying him to the point where it left him feeling suicidal.

"For the past seven years, I’ve lived with a deep, unhealed trauma," said Costello, who stars in Project Runway.

Costello (38) went on to say that in 2014, Teigen "apparently formed her own opinion of me based on a Photoshopped comment floating around the internet which has now been proven to be false by Instagram and since taken down."

The comment in question was altered to make it appear as if Costello had used a racial slur.

Costello posted screenshots from the conversation between him and Teigen that shows that the cookbook author did not hold back with the insults and veiled threats.

The messages began with Costello asking Teigen if he can call her.

"No! I do not have anything to say to you," Teigen responded. "You will get what’s coming to you."

Costello then goes on to explain that the fake images were in fact fabricated, but Teigen plowed on.

"Good luck with that lmao hope that story keeps your already dead career going," she said.

After asking Teigen again to speak to him, Costello insists that the images are fake and that Teigen’s comments are only making the situation worse.

"Good! Racist people like you deserve to suffer and die," Teigen said to Costello. "Your career is over, just watch."

In his post, Costello also alleged that Teigen and her stylist Monica Rose had “gone out of their way to threaten people and brands that if they were in any shape or form associated with me, they would not work with any of them.”

"I didn’t see the point of living," Costello admitted. "There was no way I can ever escape from being the target of the powerful elites in Hollywood."

"I am not okay," he continued. "I may never be okay, but today, I am choosing to speak my truth."
