Jessica Biel and Justin TimberlakeReports are surfacing that Justin Timberlake ended his relationship with Jessica Biel because he was "miserable" and wanted to "enjoy being single."

Reps for the couple claimed last week that Timberlake and Biel "mutually have decided to part ways."

But UsMagazine.com is reporting that a friend of Timberlake is telling them the singer "had been aggressively trying to end things."

The friend also disclosed, "He [Timberlake] hasn't been happy with Jessica for close to two years. You'd be surprised at how soon the love was lost on this one. Justin said he was miserable."
