Justin Timberlake - "Cry Me A River"
What Happened: With his new 20/20 Experience album reaching double platinum and his blissful marriage to Jessica Biel, JT seemingly has it all. But there was a time in the "Mirrors" singer life when his heart was shattered. In his now infamous diss song, Justin called out his ex girlfriend, pop star Britney Spears, airing her dirty laundry when he accused her of cheating on him, with several different men.
Most Revealing Lyric: "You don't have to say/ what you did I already know/ I found out from him/ Now there's just no chance/ With you and me/ There'll never be/ Don't it make you sad about it?"
