I think Lady GaGa because Harry Potter isn't on commercials anymore. And also, Harry Potter isn't on the radio! (example: KISS108, JAM'N 94.5, etc.)
Lady Gaga but I don't like her so...yeh. But I don't like Harry Potter either..
Lady GaGa is more famous but Teen Top is way better than both of them.
The two have never met ;) There is no mention of any "Lady gaga" in the Harry Potter novels.
In my opinion, Hermione Granger is more famous, but some peoples opinion is Lady Gaga, which is not in my case.
No. Evanna Lynch played Luna.
