Michelle Trachtenberg, celebrated for her roles in 'Gossip Girl' and 'Buffy the Vampire Slayer', tragically passed away at the age of 39, with her family opting against an autopsy for religious reasons.

While the specific reason for her transplant remains unclear, alcohol-related liver disease is a leading cause of such procedures in the U.S.

Transplant recipients typically require lifelong medication to prevent organ rejection, particularly critical within the first six months post-surgery.

Despite her challenges, friends described Trachtenberg as kind and supportive, reflecting on her struggles as a child star and her reclusive nature in recent years.

Taylor Momsen remembered Trachtenberg as 'sassy, bold and sensitive,' highlighting their close friendship and support for each other.

Recently, police sources revealed that Trachtenberg had undergone a liver transplant and may have faced complications related to the surgery.

In her later years, Trachtenberg had largely stepped away from the public eye, with her last notable role being in the 2023 reboot of 'Gossip Girl'.

Her friendship with Eugenie, which began around 2013, was marked by shared experiences, including attending a New York Knicks game together.

Trachtenberg's last public appearance occurred just a week prior to her passing at Sartiano's restaurant in SoHo.

She was set to attend a benefit screening of her final film 'Spyral' on March 12, which supports mental health charities, either in person or via Zoom.

The news of Trachtenberg's death has sparked discussions about the future of the 'Buffy' reboot, which Sarah Michelle Gellar confirmed is in development.

Throughout her career, Trachtenberg transitioned from child star to adult roles, speaking out against inappropriate behavior in Hollywood.
