“I've had a lot of ex-boyfriends betray me - a**holes, we all have them... I began to write a song about an ex-lover who betrayed me, who loved heavy metal music. And then I thought about the biblical implications and how Judas was the betrayer. And once I thought about what I wanted to do with the video... Judas didn't really betray Christ because he was part of the prophecy. So I thought a more liberating way to tackle the message of the song - we attack the idea by saying my ex betrayed me and this person haunts me, but I forgive them," Lady Gaga told Nicola Roberts for Britain's MTV.
Ironically, she revealed that her song “Judas" is inspired by her ex-boyfriend just a few weeks after announcing her split from heavy metal drummer Luc Carl.
