Guess Justin Timberlake wasn't kidding when he sang, "This ring here represents my heart." Us Weekly is reporting that multi-hyphenate Justin Timberlake and his on-again, off-again movie star girlfriend Jessica Biel are engaged to be married. Insider sources reveal that JT popped the question during a snowboarding trip in the mountains of Wyoming.

Timberlake and Biel were first linked together in early 2007; the couple split for a brief period last year but quickly reconciled and began considering marriage.
