Pop star Justin Timberlake said on Twitter he didn\'t use a slur to describe his Louisiana-born ex-girlfriend Britney Spears at a weekend concert in New Orleans. \"Sometimes in life, you think you found the one. But then one day you find out, that she is just some [expletive]!\" Hollywood Life quoted Timberlake as saying at this past Saturday\'s concert as he introduced his breakup anthem, \"Cry Me a River.\" The remark was met with a backlash online from fans who thought he was trash-talking Spears, who can be heard saying, \"It\'s Britney, [expletive],\" in two of her hit songs -- \"Gimme More\" and \"Scream & Shout.\" \"Ok. I see you. Wouldn\'t disrespect ANYONE personally. Ever. #Relax #ItsBritney[Expletive] I do love that saying though*with accent* #Respect,\" Timberlake tweeted to upset fans. The couple dated for three years and broke up in 2002. Spears went on to have two sons with her now-ex-husband Kevin Federline. Timberlake is now married to actress Jessica Biel.
