Hollywood is honoring the life and career of actress Michelle Trachtenberg.

Rosie O’Donnell, Trachtenberg’s “Harriet the Spy” costar, issued a statement to US Weekly about the passing.
“Heartbreaking,” she told the outlet. “I loved her very much. She struggled the last few years. I wish I could have helped.”

James Marsters, another “Buffy” costar penned a sweet note about the actress.
“My heart is heavy today. We have lost a beautiful soul. Michelle was fiercely intelligent, howlingly funny, and a very talented person. She died much too young, and leaves behind scores of people who knew and loved her,” he wrote on Instagram alongside a photo of the two.
“My heart goes out to her family who are good people and are suffering the greatest loss anyone could bear. I hope everyone can give them space to heal in this most difficult time.
Godspeed Michelle. You are missed.”
