During his performance in Las Vegas, Justin Timberlake tried to warn people before performing "Cry Me a River", a song said to be about his ex-girlfriend Britney Spears.

"No disrespect," Justin said before the song started.

Timberlake, who dated the pop star from 1999 to 2002, released the song the same year they split. The music video for the song featured an adulterous woman who looked almost identical to Britney.

In Britney Spears' memoir, "The Woman in Me," she admitted that she cheated on Timberlake "once." with choreographer Wade Robson. Spears also claimed that Timberlake cheated on her several times with "another famous person," whose identity she did not reveal.

In the book, Britney goes into detail about her relationship with Justin, where, among other things, she confessed that she had an abortion because Justin thought they were too young to have children.

Timberlake rushed to Mexico with his wife, Jessica Biel, and their sons Silas and Phineas last month after the backlash he received following the publication of Britney's book.

He is trying to get back into the limelight, despite the negative comments on his Instagram.
