Chrissy Teigen has broken her month-long silence on social media to admit that she is "ashamed" over vile tweets she sent to Courtney Stodden when they were just a teenager.
The 35-year-old cookbook author, who is married to John Legend, also admitted that she has been "sobbing" through private apologies to others she has hurt over the years.
She also claimed that she is "no longer the person who wrote those horrible things" and that she "got therapy".
This comes after Chrissy was blasted last month after it was revealed that Chrissy had told the American reality star to kill herself on Twitter in 2011.
Chrissy had sent Courtney, who now identifies as non-binary, a string of abusive messages when they were still a teenager.
They included telling them to die, to take their own life and to "go to sleep forever".
Courtney, who is now 26, was just 16 years old at the time.
Chrissy first responded to the reports in a string of tweets on May 12 in which she apologised for her behaviour and claimed that she had tried to connect with Courtney privately - something they have denied.
Since then, her Twitter account has remained silent but Courtney shared a tweet today, in which a link to a longer post was attached.
She tweeted: "Hi again."
In the post, Chrissy wrote that it had been "a very humbling few weeks" in which "not a single moment has passed where [she hasn't] felt the crushing weight of regret for the things [she's] said in the past".
Chrissy once again claimed that she has "apologised publicly to one person" but that she is in the process of privately reaching out to the people she has insulted over the years.
"I understand that they may not want to speak to me," she wrote. "I don’t think I’d like to speak to me. (The real truth in all of this is how much I actually cannot take confrontation.) But if they do, I am here and I will listen to what they have to say, while apologizing through sobs."
She continued: "There is simply no excuse for my past horrible tweets. My targets didn’t deserve them. No one does. Many of them needed empathy, kindness, understanding and support, not my meanness masquerading as a kind of casual, edgy humor.
"I was a troll, full stop. And I am so sorry."
Chrissy went on to say that she is thinking of the friends she has disappointed and that she had enjoyed using social media when she first started to "find kindred spirits" and "snark at some celebrities".
"In reality, I was insecure, immature and in a world where I thought I needed to impress strangers to be accepted," she wrote. "If there was a pop culture pile-on, I took to Twitter to try to gain attention and show off what I at the time believed was a crude, clever, harmless quip. I thought it made me cool and relatable if I poked fun at celebrities."
The model admitted that she not "cringes to [her] core" and gets "sharp, stabbing pains" in her body when confronted with some of the things she has said.
But she insisted: "I wasn’t mean in my everyday life. More than once, someone would come up to me and say, 'You’re so much nicer in person.' Why was that not a huge red flag?
"But I took it in and tossed it aside. I did book signings where girls would call me a bad a** b*****, and I’d stretch my arm toward them as they walked away, looking at my friends and saying, 'I promise, I’m not!'"
Chrissy continued that she "gets it now" and that she is "not seeking or deserving any sympathy", adding that there is "no justification for [her] behaviour".
She said: " The truth is, I’m no longer the person who wrote those horrible things. I grew up, got therapy, got married, had kids, got more therapy, experienced loss and pain, got more therapy and experienced more life. AND GOT MORE THERAPY."
The model also referred to her husband John and how they both "preach kindness" to their son and daughter every day.
Chrissy wrote: "My goal is to be so good that my kids will think this was all a fairy tale. Not the fake good. The good that has the best intentions, the good who wakes up wanting to make her friends, family, her team and fans as happy as possible. The good who will still f*** up in front of the world but rarely, and never not growing only more good from it."
She continued to say that she would keep on working hard to be the best version of herself and that the "world needs more kindness".
Chrissy finished the post: " I won’t ask for your forgiveness, only your patience and tolerance. I ask that you allow me, as I promise to allow you, to own past mistakes and be given the opportunity to seek self improvement and change."
