The former child star was found dead in the bathtub of his home less than 24 hours before his brother Nick Carter was due to perform with the Backstreet Boys on their DNA tour. He was only 34 and had a history of drug addiction.
The group who have been together 29 years thanked the fans for all their support and said they were performing with "heavy hearts" as they had lost one of their family members the day before and wanted to find a moment in their show to recognize him. Nick was choking back the tears as he sang.
Aaron posted an Instagram story just a week ago as he painted his house.
