Four months after they called it quits, Justin Timberlake and Jessica Biel have reportedly rekindled their romance. The couple split up in March after four years together but a source tells US Weekly they have been talking the whole time they were apart and decided to give it another shot. Timberlake allegedly realized single life was not what it was cracked up to be. The source adds that the duo are just spending time together and taking things slowly. On Sunday, the couple visited the Black Hoof restaurant in Toronto together.
