'Social Network' Star Justin Timberlake Doesn't Use Facebook

Justin Timberlake stars in the new film "The Social Network," about the origins of the multi-billion-dollar website Facebook, but the actor/musician doesn't even have a FB page!

"I don't have a lot of time in between work... And so much of that time goes to watching Sports Center," Justin joked.

"I think your life is as private as you choose it to be," Timberlake added. "That's the beauty of this country, freedom of choice."
