Michelle Trachtenberg, the celebrated actress known for her roles on Buffy the Vampire Slayer and Gossip Girl, tragically passed away on February 26, 2025, at the age of 39. The news of her death has sent ripples of shock throughout the entertainment industry, particularly among her fans and colleagues who cherished her talent and spirit. At the time of her death, Trachtenberg was involved in a long-term relationship with Jay Cohen, her boyfriend since around 2020.
Cohen, who is well-regarded within Hollywood circles as both a talent agent and producer, became an important figure in Trachtenberg's life. The couple maintained a low profile during their relationship, which began after Trachtenberg signed with the Gersh Agency, where Cohen is the head of film finance and distribution. Their connection was solidified over the years, culminating publicly on Valentine's Day 2023 when Trachtenberg shared on her Instagram, "Happy Valentine's Day to the man who sits still long enough for me to paint his face," alongside a whimsical Halloween photo of the two dressed as Dr. Jekyll and Mr. Hyde.
While their relationship was predominantly private, Cohen occasionally shared glimpses of their bond on social media. For example, he lovingly referred to Trachtenberg as his "valentine" when he posted about their shared moments together. They celebrated each other’s milestones quietly, yet it was evident from their posts how deeply they cared for one another. Cohen, now left grieving, had been spotted at Trachtenberg’s family home shortly after her passing. He remained tight-lipped about the tragedy but stated to DailyMail.com, "The family will not be commenting on the tragedy," showcasing the sensitive nature of their loss.
Professionally, Jay Cohen has had quite the career arc. Initially starting as an investment banker on Wall Street, he later made the leap to Hollywood, where he found his niche as both producer and talent agent. "I started out as an investment banker in New York, made my way to LA, financed some movies for people by accident, so I learned how to make movies," Cohen recounted at the 2015 Toronto International Film Festival. His notable works include Swimming with Sharks and Bride Wars, and he co-founded his own production company, adding to his impressive credentials.
Throughout their nearly five-year relationship, Cohen and Trachtenberg had kept things relatively under wraps. Their public displays of affection, such as the charming posts on social media, were rare but heartfelt. Perhaps this cultural approach to their relationship was part of what endeared them to each other; they both had experienced significant journeys, having faced personal battles outside of their public personas. Tragically, Trachtenberg had recently undergone a liver transplant, and the circumstances surrounding her death are still under investigation.
Jay Cohen is also a proud father to two daughters, showing his commitment not just to his work but to his family. He often shared his experiences with his daughters, Rachel and Lili, on social media, detailing family vacations and milestones. Just months prior to Trachtenberg’s passing, he gushed over his youngest daughter’s wedding on Instagram, indicating his strong family values and the happiness he derived from them. The heartfelt celebrations of family were natural interactions for Cohen, who now finds himself mourning the loss of his beloved partner.
Michelle's sudden departure has left many contemplating her legacy. Known not only for her memorable roles but her warmth and humor, she rapidly endeared herself to fans and colleagues alike. Many took to social media following her passing to express their heartbreak and appreciation for the talented actress, including co-stars from her past projects who honored her memory with emotional tributes.
Trachtenberg's life, though cut short, was filled with bright moments and accomplishments. From her breakthrough role as Lily Montgomery on All My Children to her iconic portrayals as Dawn Summers on Buffy and Georgina Sparks on Gossip Girl, her contributions to the industry are imprinted on the hearts of many. Jay Cohen's resilience will undoubtedly be tested as he navigates this immense grief following Trachtenberg's untimely death. Together, they found joy and laughter, which will linger as cherished memories for those who loved her.
Though the exact cause of Trachtenberg's death has yet to be firmly established, as authorities continue to investigate, it has been confirmed there was no suspicion of foul play. Each moment shared by Cohen and Trachtenberg now holds significant value as fans and friends alike reflect on their time together.
