Aaron Carter

Hilary and Aaron dated in the early 2000s.

Nick cited addiction and mental illness as "the real villain."

Aaron Carter previously appeared as a guest on Hilary Duff's early 2000s teen show, 'Lizzie McGuire.'

Former tour mates, co-stars and famous friends are sharing their memories and condolences online.

The singer is survived by his 11-month-old son.

Carter later claimed he "trolled everybody."

Aaron made the announcement on Instagram.

The former teen pop idol is going to be a dad!

The 2000s had some pretty questionable celebrity fashion moments.

Because even famous families fight sometimes.
