Ryan Adams has penned an apology letter for his ex-wife Mandy Moore and other former relationships admitting to the harassment and emotional abuse allegations levelled against him by multiple women last year.

In a letter that was published by Mail Online on Friday, Ryan Adams apologised for his past actions and said that realising the harm that he has caused has "wrecked" him.

"There are no words to express how bad I feel about the ways I've mistreated people throughout my life and career. All I can say is that I'm sorry. It's that simple. This period of isolation and reflection made me realize that I needed to make significant changes in my life," the musician said.

"I've gotten past the point where I would be apologizing just for the sake of being let off the hook and I know full well that any apology from me probably won't be accepted by those I've hurt. I get that and I also understand that there's no going back," the 45-year-old continued.

Adams's apology comes over a year after seven women including his former wife Mandy Moore and an underage singer accused him of being manipulative, controlling, and obsessive. In the New York Times report that was published in February 2019, Adams was accused of using his influence to stifle the victims' ambitions and subjecting them to harassment and abusive texts.

Moore, who tied the knot with Adams in 2009 and split in 2016, had claimed in the article that her former husband was psychologically abusive, and "music was a point of control for him." The "A Walk to Remember" star married American singer Taylor Goldsmith in 2018.

At that time, Adams had denied the claims via his attorney Andrew Brettler, stating that the allegations were "outlandish" and "false" made by "disgruntled individuals" who blamed him for their failed career.

However, in his recent apology, the "Do You Still Love Me" hitmaker admitted to his wrongdoings and stated: "To a lot of people this will just seem like the same empty bull***t apology that I've always used when I was called out, and all I can say is, this time it is different. Having truly realized the harm that I've caused, it wrecked me, and I'm still reeling from the ripples of devastating effects that my actions triggered."

The singer said that he realises he "will never be off the hook," and would take professional help in an "effort to be a better man." "I hope that the people I've hurt will heal. And I hope that they will find a way to forgive me," Adams added.
