Aaron passed away on Saturday, November 5 (US time). According to CBS News, the singer was found dead in his home in Los Angeles, California.
"We are extremely saddened and shocked to confirm the passing of Aaron Carter today," Aaron's manager Roger Paul said in a statement as reported by CBS News.

Following his passing, Aaron's brother, Nick Carter of Backstreet Boys also took to social media to pen a message for his late brother.
"My heart is broken. Even though my brother and I have had a complicated relationship, my love for him has never ever faded. I have always held on to the hope that he would somehow, someday want to walk a healthy path and eventually find the help that he so desperately needed," he posted on social media.
He added, "Sometimes we want to blame someone or something for a loss, but the truth is that addiction and mental illness is the real villain here. I will miss my brother more than anyone will ever know. I love you Chizz. Now you can finally have the peace you could never find here on earth….I love you baby brother."
