William Stewart Wins Landmark Defamation Suit Against Tiffany Haddish

After spending nearly a decade under the shadow of allegations popularized in Tiffany Haddish’s memoir The Last Black Unicorn, William Stewart has emerged with his reputation legally restored following a major defamation verdict in 2026.

For years, Stewart was publicly perceived through a single narrative—that of the unnamed antagonist described as a “monster” in the best-selling book. The memoir portrayed him as an abusive and volatile figure, shaping public opinion long after their marriage ended. However, developments in 2026 have fundamentally altered that portrayal, shifting the spotlight toward accountability in celebrity storytelling.

Stewart’s legal turnaround stems from a prolonged defamation lawsuit filed against Tiffany Haddish, co-author Tucker Max, and publisher Simon & Schuster. The case centered on the chapter titled “The Ex-Husband,” which Stewart argued contained fabricated claims of abuse and stalking presented for commercial benefit. His legal team maintained that these allegations lacked corroborating evidence and caused lasting personal and professional harm.

A critical moment came when the Texas Court of Appeals rejected attempts to dismiss the case, allowing Stewart to pursue damages. By 2026, the outcome had become a defining example of how memoirs labeled as personal truth can still face legal scrutiny when they damage a private individual’s reputation.

Beyond the book’s narrative, Stewart’s background contrasts sharply with his portrayal. A U.S. Army veteran, he built his life around military discipline and later worked as a private investigator. Skills tied to his profession were, according to court filings, reframed in the memoir as evidence of stalking behavior. Stewart stated that his legal action was driven by a desire to protect his family, particularly his mother, Elnora Daugherty, from what he described as character assassination.

Another disputed point involved the marriage timeline. While the memoir suggested a “double marriage,” legal documents confirmed one continuous marriage from 2008 to 2013. Disagreement also arose over a lost pregnancy, with Stewart presenting records that challenged how the event was described publicly.

Legal experts now view the case as a precedent-setting moment for the publishing industry, reinforcing that “creative license” does not override factual responsibility. By extending liability to co-authors and publishers, the verdict signals increased expectations for accuracy in “truth-based” celebrity works.

At 59, Stewart remains outside the entertainment industry, focusing on his career and family life. Though his estimated 2026 net worth ranges between $1 million and $1.5 million, Stewart has emphasized that restoring his name was the real victory.

As 2026 unfolds, his case stands as a reminder that even the most powerful narratives can be challenged—and that the truth, though slower, can ultimately prevail.
