Report: Jessica Biel and Justin Timberlake Engaged! (PHOTOS)

Jessica's Sexiest Looks
Miss Biel knows how to turn heads.
They’ve been on again, they’ve been off again, and now Justin Timberlake and Jessica Biel will be walking down the aisle, according to Us Weekly.

Insiders tell the magazine that Justin proposed in the mountains of Jackson, Wyoming and the pair became engaged in late December.

“Justin knows how much she loves snowboarding and the mountains, so it was the perfect place,” the source claims.

Justin, 30, has “never been happier” since proposing to Jess, 29, as he knew it was the right time to take the next step after splitting back in March 2011.

In the lead-up to Christmas, jeweler Tayloe Piggot wrote on their Facebook page: “Word on the street is that Justin Timberlake proposed to Jessica Biel at the Amangani last night.” After seeing the reaction their post caused in the media, they deleted the initial post and wrote a lengthy apology to Justin and Jessica, saying:

“Again – our most sincere apologies to Justin Timberlake and Jessica Biel. We cannot believe where this rumor, which started out as (seemingly innocent) news that had been circulating in Jackson Hole, has been blown into a massive gossip event. We hope that Justin and Jessica enjoyed their visit to our town and are so sorry that it has ended up with this fiasco. We prefer to remain the sleepy art gallery and will be posting about pretty jewels from now on…”

Biel and Timberlake began dating in 2007. Throughout their relationship, they have made it a point to keep their relationship private, hardly ever attending events or premieres together.
