Oh please, this guy sounds like a nasty little bitch. He was ONE of Gaga's producers on The Fame and she is working with other people now, hardly unusual in the music world - especially with a major sound change such as from The Fame to Born This Way (one is pop pap with a few decent tunes, the other is a glorious genre mashup of everything from dance to rock). To be clear, Gaga writes all her own lyrics and melodies (one of the rare real musicians in pop), and she always gives credit to her producers. What's up Rob? She didn't want you to work on Born This Way so you are getting your knickers in a twist?
