Why are Lady Gagas lyrics way off from her song?

i was reading the lyrics from the booklet and listening to the song Heavy Metal Lover and i noticed that it says "filthy pout" but the lyrics say "flithy shout" also at the end of the song it say "baby we were born this way" but in the lyrics it say "because we were born this way". is it me or does it really say it like that ? and if they did why would they sing it different in the song?
