The time has come to make it official. Pop superstar Justin Timberlake, 30, proposed to his girlfriend of four years, former 7th Heaven actress Jessica Biel, 29.

While it's reasonable to think the tech-savvy Timberlake would have gone all out for the big question, he instead popped the question according to Biel's tastes — quietly, and surrounded by nature — sometime in late December. After a rocky road that has seen them break up as recently as March of 2011 and reemerge as one of Hollywood's hottest couples, Timberlake proposed in the picturesque mountains of Jackson, Wyoming.

"Justin knows how much she loves snowboarding and the mountains, so it was the perfect place," a source told UsWeekly.
