Timberlake and Biel first started dating in 2007 but mutually decided to part ways in March 2011. Despite the breakup and the surfacing rumors about a relationship with his Friends with Benefits co-star Mila Kunis, Timberlake always spoke highly of Biel. “She is the single-handedly most significant person in my life,” Timberlake told Vanity Fair in June, mid-split. In November 2011, Timberlake and Biel confirmed that they had rekindled their relationship. “When they reunited they had a conversation about taking the next step,” said the source.
