Justin Timberlake's Vegas Performance Sparks Britney Spears Backlash Hint

During his performance at the opening of the Fontainebleau in Las Vegas, Justin Timberlake hinted at the backlash he received from ex-girlfriend Britney Spears by cautioning the audience before singing his hit song "Cry Me a River." The song, which was mentioned in Spears' recent memoir, "The Woman in Me," was about their breakup. Spears revealed in her book that she cheated on Timberlake and had an abortion because he allegedly did not want to be a father. Timberlake had not publicly reacted to Spears' remarks until now.
