Justin Timberlake is a very talented musician and actor but he is quick to point out that he is not a relationship expert. Speaking to The Hollywood Reporter at the New York premiere of Friends With Benefits on Monday, Timberlake pointed out that he should not be giving anybody love advice because he is a single male. The actor called it quits with Jessica Biel in March after dating for four years although sources say the duo are quietly seeing each other again and have decided to give their relationship another shot. Before Biel, Timberlake was linked to actress Cameron Diaz and Britney Spears.
