@ Hudson Morrigan:

What the hell does her fave have to do with this? Did s/he even compare the two? I don't care how much of an X-Tina hater you are, it's foolish to deny that she has way more vocal talent than Katy will ever have. So now anyone who's a fan of Christina's cannot ever critique other singers, even when they're less talented than her or the criticisms actually have a grain of truth to them? You really come off as an immature asshole now. Sit the fuck DOWN.

Anyway, I'm not really fond of this version. Granted I don't like the original, but Gaga's voice is the only good thing about the song. Can't say the same for Katy, unfortunately. She should stick to singing her own songs or find more vocally suitable songs to cover.
