The two broke up in March after four years together. But now, Timberlake, 30, and Biel, 29, have supposedly been seeing each other again, but trying to keep things quiet. Says a source:

    "They have been talking the whole time and decided to give it another shot. Jessica really wanted to get back together with him and Justin realized single life is not what it's cracked up to be."

The source says the two are now taking things slowly. On July 3, the pair were seen sharing pork tacos at the Black Hoof restaurant in Toronto.

At the time of the break up, reports were that Biel threw Timberlake a surprise birthday party and gave an emotional speech, which made him uncomfortable. Rumors of a split started when he was accompanied by his mother to the Oscars, while Biel was nowhere in sight.
