Michelle Trachtenberg underwent a liver transplant shortly before her death at age 39.
Sources told The Post Wednesday that the actress recently had surgery.
Although the “Gossip Girl” alum’s cause of death remains unclear, insiders said her passing is not being investigated as suspicious.
The “Ice Princess” star’s mom, Lana Trachtenberg, found Michelle Wednesday morning around 8 a.m. in her New York City apartment.
Page Six has reached out to the New York coroner’s office and Michelle’s rep for comment.
Last year, the “Buffy the Vampire Slayer” alum sparked health concerns with an Instagram selfie — and clapped back at “haters” in the comments section.
“Explain to me how I look sick,” she wrote in January 2024. “Did you lose a calendar and not realize I’m not 14. I’m 38. How sad for you to leave such a comment.”
Michelle noted in a separate post that she had come across “several comments” regarding her looks.
“I have never had plastic surgery I am happy and healthy,” the “Ice Princess” star wrote at the time, telling trolls to “check” themselves before commenting.
