The Role: No word yet on what Bieber will be doing, but he'll almost certainly be playing himself given the nature of the first Zoolander movie, and the hilarious potential that such a part has. Why It's Unexpected: One of the most controversial (and depending on who you ask, loathed) pop singers in history landing a part in a popular Hollywood comedy? It's certainly a daring move from co-writer-director Ben Stiller, who is surely aware of the furore a Bieber cameo is going to cause. Will It Work?: For better or for worse, yes. He'll either be hilarious and acquit himself, or he'll be a major douche and the Internet will get to validate its long-held opinions on him. Either way it'll probably be comic gold: it just depends on whether it's the intentional kind or not.
