Michael Costello has said that he was left "traumatized" after being "bullied" by Chrissy Teigen.
The fashion designer took to Instagram on June 15 to share his story of how he was "blacklisted" from Hollywood after being falsely accused of using a racial slur and was left so traumatized that he considered suicide.
He said that he was opening up about what happened to him in 2014 in a bid to "heal", writing on Instagram: "For the past 7 years I've lived with a deep, unhealed trauma. I didn't share this with anyone because I was living in fear."
He said that Teigen accused him of being racist after a false, photoshopped Instagram post was made from his account - an accusation she was backed up with by fellow stylist Monica Rose.
Despite repeatedly telling the pair that the post was fake, he claims that they repeatedly bullied him online and interfered in his personal life, too.
Costello shared an alleged conversation between himself and Teigen where he sent her his phone number and wrote: "I am suffering from this more than you can imagine."
In response to this, Teigen replied: "Good! racist people like you deserve to suffer and die. You might as well be dead. Your career is over, just watch."
Costello said that people frequently told him that Teigen and Rose had "gone out of their way" to threaten people and brands by, for example, saying that they wouldn't wear their clothes again if they collaborated with him, which resulted in a lot of lost work.

Costello said that after the incident, he frequently considered suicide as he thought there would be "no way for me to ever escape this."
"As a result of what Chrissy Teigen did to me in 2014, I am not okay. I may never be okay," he wrote, before adding, "These bullies could have reached out to me anytime, but they refused. Instead, they would much rather see me suffer and laugh at my demise."
This revelation comes after Teigen apologized in a blog post for bullying people on Twitter after it came to light that she'd told a 16-year-old model to "kill themselves" in 2012.
"There is simply no excuse for my past horrible tweets. My targets didn't deserve them," she wrote. "I was a troll, full stop. And I am so sorry."
