"It's not the smartest decision," Moore said of his six-year marriage. "I did not choose the right person."
On Wednesday, Adams responded to a blogger Perez Hilton's tweet about the interview.
"She did not like the Melvins or BladeRunner," Adams wrote on Twitter. "I'm condemned from the beginning … If only I could remember the beginning, hahaha."
In a tweet now removed, Adams claimed to have been so tall that he did not even remember his 2009 wedding.
"When someone told me we were married, I thought they were joking," he said. "Then I realized how many painkillers I was taking in. Honestly, there was not enough to numb the impact, Gollygooops."
Adams responded to another tweet on Thursday that said he "probably wrote 75%" of his love songs thinking about Moore.
"Actually there is not a single song about her," Adams replied. "As not one." Done.
Later tweets made the fans worry, including Adams.
"I'm doing the best I can right now, it hurts," he wrote in an answer.
"It's real, people will leave you and your life will fall into total chaos," the singer wrote. "You'll feel like you're having a heart attack, maybe they do not even care about it."
Adams wrote on Twitter on Friday that he has been seeing a counselor and apologized for the concern he caused and his comments about Moore.
"I apologize for my comments," he said. "I was trying to be funny, but I've always chosen and I'll remember the incredible moments."
