“What I went through with Shia was the worst thing I’ve ever been through in the whole of my life,” she said in an interview withThe New York Times, going on to say that she didn’t go to police at first to not harm his career and because she “thought her account would not be taken seriously.”
“I have no excuses for my alcoholism or aggression, only rationalizations. I have been abusive to myself and everyone around me for years,” he wrote to the newspaper. “I have a history of hurting the people closest to me. I’m ashamed of that history and am sorry to those I hurt. There is nothing else I can really say.”
In a different email, however, he said that “many” of the allegations were not true but explained he owed the women “the opportunity to air their statements publicly and accept accountability for those things I have done.”

In an Instagram post on Friday, Barnettopened up about her decision to speak out publicly.
“It may be surprising to you to learn that I was in an emotionally and physically abusive relationship. it was hard for me to process too, during and after i never thought something like this would happen to me,” shewrote. “Which is why i have decided it’s important for me to talk about it and try to help people understand that when you are under the coercive control of an abuser or in an interpersonal violent relationship leaving doesn’t feel like a safe or achievable option.”
The singer added that she hopes that sharing her experience “can truly” help others not feel alone and “shed a light” on how others can help loved ones in abusive relationships.
