Tiffany Haddish opened up about her past experiences with domestic violence at the hands of her ex-husband in her The Last Black Unicorn memoir. William Stewart has come forward as the man mentioned in the book and has filed a lawsuit in an attempt clear his name.

In a lawsuit, obtained by TMZ, Stewart accused his ex of labeling him a "monster" in "The Ex-Husband" chapter of her New York Times Bestselling book.

While Haddish didn't mention her ex by name, Stewart claims that he's easily identifiable because he's the only person she's ever been married to. Per TMZ, Haddish accused her ex-husband of choking, kidnapping and stalking her throughout their five-year marriage.

She reportedly implied that Stewart's domestic abuse led to her miscarrying their unborn child. Flat out denying the "Girl's Trip" star's account, Stewart, a decorated U.S. Army veteran, accused Haddish of willingly having an abortion.

He is reportedly seeking damages in excess of $1,000,000 due to claims of libel, slander and defamation. He names the books' co-author Tucker Mack and publisher Simon and Schuster as defendants in the suit as well.

News of Stewart's decision to file a lawsuit emerged late last year.

Tiffany Haddish has yet to publicly comment on the lawsuit.
