Who Is Tallulah Willis’ Ex-Boyfriend Dillon Buss?
Dillon Buss is a film director who kept a relatively low public profile even while dating a celebrity. The couple went public with their relationship in early 2020. By May 2021, things had become serious enough for a proposal. Tallulah shared photos of the romantic backyard moment on Instagram, writing “with absolute most certainty.” Dillon proposed with an emerald-cut diamond ring, and the engagement was warmly received by her family and friends.
Their relationship lasted roughly two years and was one of Tallulah’s most significant early adult partnerships. It played out against the backdrop of her growing career as an artist, designer, and advocate, as well as the intense public attention that comes with her famous last name.
How Tallulah Willis and Dillon Buss Got Engaged
The engagement felt like a fairy-tale moment at the time. Tallulah and Dillon had been together for about a year when he got down on one knee. Social media was filled with congratulations, including warm messages from her sisters. For a while, the couple appeared solid and happy.
That changed in 2022. Tallulah later shared that the relationship ended in June of that year — a difficult period that overlapped with major personal and family challenges.
Why Did Tallulah Willis and Her Ex Split?
In a candid 2023 essay for Vogue, Tallulah opened up about the breakup. She wrote that her fiancé “dumped” her shortly after her father Bruce Willis’s aphasia diagnosis became public. At the same time, she was struggling with anorexia nervosa and had dropped to a critically low weight. The timing made the end of the relationship especially painful.
Tallulah has spoken openly about entering treatment afterward and receiving additional diagnoses, including borderline personality disorder. The split marked a turning point that pushed her toward deeper self-work and recovery. While the details of their private conversations remain between them, Tallulah’s own words make clear that the relationship ended at a moment of intense vulnerability for her.
Life After Dillon Buss: Tallulah’s New Chapter
After the engagement ended, Tallulah focused on healing. In January 2023 she began dating musician Justin Acee (who performs as Nighties). The two grew close, shared creative projects (including Tallulah appearing in one of his music videos), and announced their engagement in December 2024 after a candlelit, rose-petal proposal.
On August 8, 2026, Tallulah and Justin married in an intimate ceremony in Sun Valley, Idaho. She wore a custom Balenciaga gown that took hundreds of hours to create. The wedding marked a hopeful new chapter after years of personal challenges and family health struggles.
