Justin Timberlake and Jessica Biel are Engaged

Justin Timberlake and Jessica Biel are engaged reports Us Weekly. Congratulations!

They have been dating for 4 1/2 years. Any bets on how long this will last? Will they actually wed? I'm such a skeptic now!

But what about those Mila Kunis cellphone pictures?

From Us Weekly:

After a series of breakups and makeups, Justin Timberlake and Jessica Biel have finally decided to get married!

Several insiders tell the new issue of Us Weekly (on stands Friday) that the couple of four and a half years became engaged in late December.

Timberlake, a six-time Grammy winner, popped the question to Biel, 29, in the mountains of Jackson, Wyoming. "Justin knows how much she loves snowboarding and the mountains, so it was the perfect place," one insider explains.
