We've seen/heard ALOT of this.  Singers that cover a song from another genre of music.  THIS one is a bit weird...just because Lady GaGa is a bit odd to begin with.  For you Country fans that rarely listen to pop, let alone see pictures of the artists, there is no other artist in Country music that she compares to.  She wears various wigs, lots of flamboyant make-up, risque, scanty costumes and even has a male alter-ego.  BUT, she CAN sing.  Here's the video of Luke Bryan giving it is all, singing Lady Gaga's song, "Bad Romance".
