Britney Spears Says Justin Timberlake Cheated On Her With A Celeb

More bombshells are dropping from Britney Spears' memoir, including another one about Justin Timberlake. She writes in The Woman In Me that he cheated on her with another celebrity during their three-year relationship. Spears doesn't reveal the identity of the woman, writing that she is now married with kids and Spears doesn't want to embarrass her. It has long been rumored that cheating sparked the couple's split in late 2002, but until now it was thought to be Britney who strayed. Fans have long speculated that Timberlake's solo hit, “Cry Me A River,” was about that betrayal. The cheating bombshell follows another excerpt shared by People on Tuesday in which Britney revealed that she had an abortion after getting pregnant with Timberlake, claiming he didn't want to be a dad.
