Eminem has become the world's first person to achieve 30m Facebook fans, or likes, according to Famecount.com, the social media statistics service. The record sees Eminem achieving more likes on the social network than the entire populations of Australia and New Zealand combined.
It was just 8 months ago that Lady Gaga become the first living person to achieve 10m Facebook likes, and over the last year a number of stars have seen their Facebook fame explode. In one year, Eminem has seen his Facebook likes grow more than tenfold, from just 2.7m in March 2010. Two weeks ago Eminem overtook Lady Gaga as the most popular living person on Facebook, and last week the US rapper overtook Michael Jackson to become the most popular person of all ' living or dead ' on the network. Lady Gaga also overtook Michael Jackson in the last few days to become number two on Facebook.

Yet in the fast shifting world of social media fame Eminem can take nothing for granted. Rihanna, currently on 26.5m fans is the fastest growing star on the network. Both Lady Gaga and Michael Jackson are nipping at Eminem's heels and with her new album approaching release, Lady Gaga is certainly capable of springing surprises. Eminem is also yet to conquer the other social networks. Lady Gaga is the reigning Twitter Queen while Justin Bieber is YouTube King. Groovecount.com, which ranks music stars across multiple social networks and digital music services, currently ranks Eminem second on an aggregated basis, behind Lady Gaga.
