Britney Spears Accuses Justin Timberlake of Cheating on Her With Another Celeb

Britney Spears really isn't holding anything back in her forthcoming memoir, as the stories that have already been released indicate. According to TMZ, Britney accused her ex-boyfriend Justin Timberlake of cheating on her during their three-year romance from 1999 to 2002, which definitely changes the narrative around their entire relationship.

She's keeping the details vague

According to the outlet, while Britney does make the accusation, she doesn't go into much detail. Apparently, the woman involved is also a celebrity and has a family now, so Britney doesn't want to "embarrass" her, but she seems to have no problem embarrassing Justin.

This revelation changes a lot

When Britney and Justin broke up in 2002, we all believed it was because Britney had cheated. Justin seemed to confirm that speculation when he released the song "Cry Me a River" later that year — there was even a Britney lookalike in the video. But now this will have pop culture historians wondering if we need to rewrite the narrative.

One of Britney's songs now takes on a different meaning

Many fans speculated that Britney's 2003 song "Everytime" was a direct response to the cheating allegations based on the lyrics "I may have made it rain. Please, forgive me. My weakness caused you pain. And this song's my sorry." But could there be more to the lyrics?

This new revelation comes after a bombshell reveal yesterday

On Tuesday, it was reported that Britney had gotten pregnant during her relationship with Justin, and that he asked her to get an abortion because he felt that he was too young and not in a place to be a father.

Britney's memoir, Woman in Me, doesn't come out until Tuesday, October 24, so we'll have to wait and see what else she will reveal.
