After years of rumors, Justin Timberlake and Jessica Biel have finally called it quits. No, Jessica didn't get fed up with JT's lying, cheating ways. He actually dumped her - over the phone - say friends. Ouch. Meanwhile, Jessica is said to be in severe denial that they have split-up.

A friend told Us Weekly that the break-up actually happened about a month ago, and that when Timberlake, 28, was in New York City for Fashion Week, he was "clearly on the hunt". In fact, he was spotted out dirty dancing with a tall blonde at a NYC club.

Nevertheless, the fact that he was seen getting close with another woman is no indication that he's split up from Jess. Back in June, he was spotted in the NYC club Avenue kissing a woman that definitely wasn't Biel. Fellow club-goer Lindsay Lohan had witnessed him making out with another woman, and twittered "So dark - where's jb cheater?" Later she claimed her account was hacked, but sources say that she removed it after Justin to his people to make her life miserable.

A second source revealed to Us Weekly:

"There's no way of knowing if it's a firm breakup, because with them it's so hot and cold."

Now, let the rumors of a rekindled romance between Britney Spears and Timberlake begin! (You know they're gonna start up again sometime)
