Nick Carter “Back to Daddy Duties” in Heartwarming Family Photos

“Even though my brother and I have had a complicated relationship, my love for him has never ever faded,” he wrote on Nov. 6. “I have always held onto the hope, that he would somehow, someday want to walk a healthy path and eventually find the help that he so desperately needed.”

Nick and his sister Angel Carter have since then honored Aaron’s legacy by establishing a donation fund to support the children’s mental health organization, On Our Sleeves, of which the singer serves as an ambassador.

“Gifts fund educational content, lesson plans for schools and activities for schools and organizations,” a rep for Nick said in a statement on Nov. 14. “By honoring Aaron, you help Nick, Angel, and their family’s commitment of helping others.”
