Following news that Carter, 34, was found dead on Saturday, Duff took to social media to post a message addressed to the singer. As teen stars, Duff and Carter dated on and off for about three years.
In a note “for Aaron,” the actress, 35, reflected on her ex’s troubled life.

Duff and Carter’s relationship began in 2001, and reportedly overlapped with his romance with another teen icon of the time, Lindsay Lohan. Though he and Duff — now a mom of three who wed second husband Matthew Koma in 2019 — had called it quits for good by 2004, Carter continued to declare his love for the star.
In 2014 Carter referred to the How I Met Your Father star as the “love of my life” and shared his regret about losing her.
A spokesperson for the Los Angeles Sheriff’s Department confirmed to Yahoo that deputies responded to Carter’s home in Lancaster, Calif. on Saturday shortly after 11 a.m. Upon arrival, officers found a deceased body. Homicide is handling the investigation, which is standard procedure at this time.
