Justin Bieber Builds Up 'Never Say Never' Anticipation On Twitter With #PurpleGlasses

Is it possible that Justin Bieber is the greatest pop star of the Twitter era? Nobody else in the game uses the service better, as he deftly combines personal promotion (you always know what product is available if you follow him) with fan interaction (he's constantly re-tweeting followers and giving shout-outs to fans) and his personal obsessions (like Chuck Norris). He's a veritable Twitter ninja, and the proof is in both his sales numbers and his army of followers (he's well over six million at the moment).

His latest Twitter assault is related to his upcoming film "Never Say Never," which will be a behind-the-scenes 3-D extravaganza that helps tell the 16-year-old singer's back story and also follows him as he travels around the world on a sold out tour. You can score your special purple 3-D glasses now (along with a commemorative laminate, wristband and glow stick) via a special VIP preview package, and he has been tracking the spread of said glasses on Twitter.

All this week, Bieber has been re-tweeting followers who have posted photos of themselves wearing the Bieber-specific 3-D glasses, and he has even turned the hash tag "purpleglasses" into a trending topic. Most interesting are the photos that have been sent Bieber's way, many of which are people posing with the glasses and even more of which have a wacky edge to them. One fan put them on her cat, while another layered a whole series of photo effects over a shot of her with them on.

The best photos will end up on the "Never Say Never" preview page as well as on the movie's official Facebok hub. It's just one more example of how Bieber has won over millions not only with his killer songs and adorable good looks but also with a keen eye towards building relationships with the people who buy his albums and come see him in concert.
