Who was Michelle Trachtenberg’s boyfriend?
Michelle Trachtenberg’s longtime boyfriend was Jay Cohen, a talent agent associated with Gersh. Their relationship became public in October 2020 after sources told Us Weekly that they had been dating for more than a year. Later reporting indicated that Cohen was still Trachtenberg’s partner shortly before her death on February 26, 2025.
The available reporting describes Cohen as both Trachtenberg’s romantic partner and her talent agent or representative. Because Trachtenberg died in 2025, “was” is the accurate wording: Jay Cohen was Michelle Trachtenberg’s boyfriend, not her current boyfriend.

Who is Jay Cohen?
Jay Cohen was described in the original relationship report as a Gersh talent agent and agency partner. Us Weekly reported that he joined Gersh in 2009 to lead its Film Finance and Distribution division and identified earlier producing credits including Bride Wars, Mad Money, and Two for the Money. Those career details come from the entertainment report and should not be expanded into an independently verified biography beyond what that report states. Us Weekly’s 2020 report on Cohen provides the original description.
The safest concise description is “talent agent Jay Cohen” or “Michelle Trachtenberg’s longtime partner, Jay Cohen.” The public record reviewed for this article does not establish detailed information about his age, family, education, finances, or private life.

On February 14, 2025, Trachtenberg wrote: “Happy Valentine’s Day to the man who sits still long enough for me to paint his face. 🖤💚🩶 💋” The message accompanied a throwback Halloween image of the couple. Us Weekly’s February 2025 report and Parade’s relationship retrospective document the Valentine’s Day and earlier social-media posts.
Cohen had also shared a July 4, 2021 selfie with Trachtenberg, writing, “Fireworks every day with this one.” In February 2023, he referred to her as “My valentine,” and in March 2024, Trachtenberg posted a birthday message for him alongside a photograph of the pair in Halloween costumes.
Were Michelle Trachtenberg and Jay Cohen engaged?
There is no reliable confirmation in the reviewed sources that Michelle Trachtenberg and Jay Cohen were engaged. In October 2020, Trachtenberg posted a selfie wearing a diamond ring and wrote, “I picked the right one 😜⚡️💍,” but she later clarified in replies that the post was an April Fools joke. The ring photograph should therefore not be presented as proof of an engagement. Us Weekly’s original report records the clarification.
Were Michelle Trachtenberg and Jay Cohen married?
No marriage is reliably documented in the sources reviewed for this article. The public record supports a long-term relationship, but it does not confirm that Trachtenberg and Cohen married or had children together.
| Claim | What the evidence supports | What should not be claimed |
|---|---|---|
| Long-term relationship | Yes. Sources said they had dated for more than a year by October 2020, and later reports described them as together in February 2025. | An exact anniversary or exact total relationship length. |
| Public acknowledgment | Yes. Both shared occasional social-media posts about each other. | That occasional posts represented a complete account of their private life. |
| Engagement | Not confirmed. The 2020 ring post was clarified as an April Fools joke. | That Trachtenberg and Cohen were engaged because of the ring photograph. |

What happened to Michelle Trachtenberg’s boyfriend after her death?
Jay Cohen appeared to remain Trachtenberg’s partner until shortly before she died on February 26, 2025. On February 27, Us Weekly cited sources who said she was still with Cohen and described him as “a huge support system” during her health struggles. The statement came from unnamed sources, so it should be understood as reported source information rather than a direct statement from Cohen or Trachtenberg.
The Associated Press reported that Trachtenberg was 39 when she died on February 26, 2025, and later reported that the New York City medical examiner determined that she died from complications of diabetes, with the manner of death ruled natural. The Associated Press report on the medical examiner’s finding provides that context. The medical finding does not establish anything about Cohen’s medical knowledge, caregiving, responsibility, or private conduct, and the available sources do not support speculation about those matters.
On July 10, 2025, E! News reported that Cohen wrote publicly about grief and thanked people who had supported him. Cohen wrote: “I am so grateful to all of you who are in my life sharing our common joys, helping me with tragedies and healing from pain and grief.” E! News reported Cohen’s post after Trachtenberg’s death.
How did Jay Cohen’s work connect to Michelle Trachtenberg’s career?
Jay Cohen’s professional connection to Trachtenberg was unusual because relationship coverage also identified him as her talent agent. The original Us Weekly report described Cohen as her representative at Gersh, while also describing his work in film finance and distribution. The available sources do not explain how their professional and personal relationships were managed, so no further inference is warranted.

Trachtenberg’s best-known screen credits included Dawn Summers on Buffy the Vampire Slayer, a role documented by the Television Academy’s Michelle Trachtenberg biography. Readers revisiting her work can look for a Buffy the Vampire Slayer complete series DVD or another Buffy DVD box set; library catalog records document physical-season editions of the series, including WorldCat’s catalog record for the complete first season. This is a way to revisit Trachtenberg’s acting work, not a source of information about Cohen or their relationship.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What does the public record establish?
The strongest supported conclusion is straightforward: Jay Cohen was Michelle Trachtenberg’s longtime boyfriend and a talent agent associated with Gersh. Their relationship was publicly reported in October 2020, social-media posts showed continued affection over the following years, and February 2025 reporting indicated that they were still together shortly before Trachtenberg’s death.
The record is more limited on private details. It does not reliably establish an exact start date, marriage, children, or engagement. A careful account should distinguish Trachtenberg’s own posts and Cohen’s own later statement from claims made by unnamed sources, and it should avoid speculation about the couple’s private life.
