The model and TV personality, who had more than 13.7 million followers, announced that she would be leaving the site in a series of tweets on Wednesday.
“But it’s time for me to say goodbye. This no longer serves me as positively as it serves me negatively, and I think that’s the right time to call something.”
Teigen’s account was popular for its mix of jokes about her husband John Legend and their children, their playful banter on the site, funny observations about assorted topics and fierce retorts for those she disagreed with or who criticized her.
That reputation is at odds with who she really is, the model and cookbook author wrote.
“My life goal is to make people happy,” she wrote. “The pain I feel when I don’t is too much for me. I’ve always been portrayed as the strong clap back girl but I’m just not.”
Last year, the model had used Twitter — among other social platforms — to announce that she and her husband, John Legend, had lost their child following pregnancy complications.
Teigen is known for her witty Twitter comebacks, and has had several colorful spats which have trended on the platform — including with former US President Donald Trump, who she called a “p* a** b*” after the president branded her as Legend’s “filthy mouthed wife” following discussions about criminal justice reform.
While her candor about the loss of their son won praise, some criticized her for putting such painful moments on social media.
She wrote Wednesday that she’s experienced so many attacks from low-follower accounts that she’s “deeply bruised.”
In one of her final posts, she told her followers to “never forget that your words matter.”
“Live well, tweeters. Please know all I ever cared about was you,” she added.
Teigen’s Instagram account, with more than 34 million followers, remains active as does Legend’s Twitter account, with 14 million followers.
