Cry her a river.
Britney Spears reportedly claims Justin Timberlake cheated on her during their relationship in her “The Woman in Me” memoir, according to TMZ.
The outlet reported Wednesday that the “Toxic” singer does not name the other woman in her book.
The former couple dated from 1999 to 2002, with Timberlake’s post-breakup “Cry Me a River” music video leading many to believe that Spears, 41, was unfaithful during their time together.
The *NSYNC member, 42, never directly accused his ex of any indiscretions, and she has yet to speak out — seemingly until now.
Timberlake’s rep didn’t respond to Page Six’s request for comment.
Although the Princess of Pop’s memoir doesn’t hit shelves until Oct. 24, People published excerpts Tuesday about the “Crossroads” star’s decision to shave her head, alleged fat-shaming from dad Jamie Spears and more.
In addition, Britney revealed she had an abortion while in a relationship with Timberlake in late 2000, claiming he “definitely wasn’t happy about the pregnancy” and “didn’t want to be a father.”

She wrote, “I agreed not to have the baby. I don’t know if that was the right decision. If it had been left up to me alone, I never would have done it.”
Britney, who went on to welcome sons Sean Preston, 18, and Jayden, 17, with Kevin Federline, called the termination of the pregnancy “one of the most agonizing” experiences she has had.
Page Six reported Monday that the “SexyBack” singer was “concerned” about Britney’s memoir release, according to multiple sources.
“He’s very curious what she’ll reveal from their relationship,” one alleged. “It’s eating at him.”
However, a publishing insider insisted that the book was “not a takedown,” but instead a “chance to tell her empowering story and … nothing more than that.”
Timberlake notably stood by Britney amid her conservatorship battle, writing via Twitter that everyone should “be supporting” her in June 2021, five months before her court battle ended.
Since Britney’s bombshell book revelation about him, “The Woman in Me” has shot to No. 1 on Amazon’s bestsellers list ahead of its release.
