Charlie Sheen, Rebecca Black and Lady Gaga were some of the most talked about personalities online in 2011, but who should we watch out for in 2012? When it comes to actors and personalities last year, it seems the American contingent are leading the way (Mr Jackie Chan slips in there too!) No British celebs though, not even the boy wizard Daniel Radcliffe! (probably doesn't help that he doesn't have an official Fan Page - if you're reading this Daniel, give me a call). So take a look at the fastest growing personalities on Facebook, see what they've been talking about and what their fans say about them too.
