Hilary Duff Is 'Deeply Sorry' After Aaron Carter's Death

Singer Hilary Duff is mourning the loss of Aaron Carter, who was reportedly found dead in a bathtub of his L.A. home on Saturday afternoon.

Not many details have been disclosed about his death so far; however, it's a shocking end to the 34-year-old brother of Nick Carter. Although he had started out his career as a pop idol himself, the "I Want Candy" singer struggled with mental health, drugs, and alcohol and was even pulled over for a suspected DUI only days before his death.

Many have been taking to social media to mourn his passing, including his ex, "How I Met Your Father" star Hilary Duff.

In a brief message on Instagram, the married mom-of-three wrote, "For Aaron-I'm deeply sorry that life was so hard for you and that you had to struggle in front of the whole world," she wrote. "You had a charm that was absolutely effervescent ... boy did my teenage self love you deeply."

"Sending love to your family at this time," she concluded. "Rest easy."

Their relationship reportedly began in 2001. They two reportedly dated on and off for three years, although there were rumors that their relationship overlapped with his relationship with "Mean Girls" star Lindsay Lohan.

Although the "Lizzie McGuire" star married her second husband, Matthew Koma, in 2019, it seems that Carter still had some regrets about the way their relationship ended.

"I don't know who she is today, she doesn't know who I am today, but I would sweep her off her feet if I ever got a chance to again and fix what I did wrong," he told Entertainment Tonight in 2014.

Reality star Paris Hilton tweeted, "Sad to hear about the news of @aaroncarter ? He was always kind to my family and I. He had a good heart. Gone way too soon. ?Sending my thoughts and condolences to his loved ones and family. RIP ?."

Singer Diane Warren tweeted, "Fame at a young age is often more a curse than a blessing and Surviving it is not easy. RIP Aaron Carter??."

Disney star Christy Carlson Romano tweeted, "Incredibly sad about the passing of Aaron Carter. My thoughts and prayers go out to his friends and family. ?️."

Loni Love tweeted, "Met Aaron Carter in 2018, funny, talented and cool. I felt that he was trying....he really was just trying to be happy. I'm sorry to hear of his passing.. Condolences to his family and fans ?."
