JUSTIN BIEBER HELPS MATT LAUER JOIN TWITTER

Justin Bieber wasn’t just a guest on Friday’s “Today Show.” He was also a Twitter teacher for anchor Matt Lauer, who just joined the social media site.  Without knowing how to send out his first tweet, Lauer gave his iPhone to The Biebs, who instead of just firing off a regular first message, used the opportunity to once again plug his upcoming “Believe” album.
