Well, first Lady Gaga asked Weird Al to parody one of her songs (like he used to do for Michael Jackson and Madonna) but when she heard it she didn't like it. So, Weird Al released it anyway (along with the story about how she backed out) and now it looks like she might actually approve it. Which means a hilarious music video is coming soon. But first, you can listen to the song, along with the lyrics.
Classic Weird Al! Spot on parody.
