I think the only reason why Eminem has more Facebook likes than Gaga and why Rihanna (and also Shakira) are coming for her wig is because of the fact that Gaga still has that certain 'gay' vibe about her. Even though she has plenty of straight male fans.
You could say the same about Bieber who's behind with Facebook likes and has the certain 'tween' vibe. Both Gaga and Bieber are clearly the most relevant stars out there right now but both will get / are getting their wig snatched on Facebook.
Therefor I declare all the Facebook likes less relevant than the amount of Twitter followers.
