Kanye West has only been on Twitter for a short time, but the rapper is already something of a staple on the site. In one of his many fascinating moves, Kanye opted to only follow one person: Justin Bieber! Over the the weekend the two stars (both pictured) sparked a friendship via tweets when Kanye posted, "Your album good @Justinbieber Playing it at my crib now" and the Biebs responded with, "might sound crazy 2 u but even having this convo is living the dream. thanks."
Unlike Kanye, actor/funny man Steve Carell is sadly not on Twitter. It's especially a bummer today, considering the "Dinner For Schmucks" star won't get to see all the birthday messages his friends and co-workers have left for him on there. Rainn Wilson, Steve's co-star from "The Office", wrote a very Dwight-like birthday wish, as he tweeted, "Happy Birthday Steve Carell! You're a 47 year old big hairy triangle of a torso. But what a torso!"
