Justin Timberlake debuts new hair at the Grammy Awards

Forget "The 20/20 Experience." Justin Timberlake debuted a new (flatter) hairdo at the 55th Annual Grammy Awards.

The 'Suit & Tie' singer presented a slick, straightened hairstyle on the red carpet; a far cry from his famous 'N Sync curls and more lately, a super short buzz cut.

We're not really digging his new 'do, and it seems his wife, Jessica Biel, isn't a fan either since she was not on the red carpet by his side. Although he really wears that Tom Ford suit well.

But Timberlake may not have a choice in how he styles his hair as he is currently working on a new movie, the crime thriller "Runner Runner" starring Ben Affleck and Gemma Arterton. Let's hope that it's Affleck forcing him to use the flat iron and not a personal decision.

And just because we can, check out a photo gallery of Timberlake's most famous hairstyles. We think we prefer the cornrows he sported in 2000.
