Lady Gaga turned Weird Al down the first time he asked her if he could parody her song Born This Way.
She has since changed her mind.
Having Weird Al parody your song is a compliment of the highest degree. Even if the song is silly, Weird Al does everything tastefully. I can't imagine why she turned him down the first time.
Go to Youtube and check out Perform This Way you'll get a laugh, because it is more a lampoon of Gaga than the song...which for the most part stinks.
Weird Al, at least makes it worth listening to.
