Justin Timberlake, Jessica Biel are reportedly engaged Is Justin Timberlake ready to give Jessica Biel his last name? That was the talk Wednesday: The on-and-off couple of nearly five years are reportedly engaged. Timberlake is said to have popped the question over the Christmas holiday in Jackson, Wyo. "Justin knows how much she loves snowboarding and the mountains, so it was the perfect place," one source told Us Weekly, which claims several insiders have corroborated the proposal. After ending another go at their relationship last summer, Timberlake and Biel took up again mid-fall as the actress made rounds with Timberlake promoting his film "In Time." The pair made a public show in November at the GQ Men of the Year party. The latest make-up sparked a serious discussion, Us says. "When they reunited, they had a conversation about taking the next step," another source tells the mag. Reps for the couple did not immediately return requests for comment. Biel recently appeared in the ensemble comedy "New Year's Eve." Timberlake spent most of his 2011 promoting various film projects.
