lady gaga. hands down. :)
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.)
That is a hard question but harry potter, or daniel, is way more famous than lady poop-poop.Harry Potter
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.
