Justin Bieber to Join Lady Gaga for New Year’s Eve to Make 2012 Best Hair Year Ever

No one wear a hat this year — the hair-a-thon is about to go off

2012 could be a very good hair year: Justin Bieber will join the always well-coiffed Lady Gaga for "Dick Clark's New Year's Rockin' Eve."

Oh, pardon us: That should've said "Dick Clark's New Year's Rockin' Eve with Ryan Seacrest." Who also has very nice hair.

The Beebs joins the previously announced The Goggs for the airing, which will be the show's 40th.
