Lady Gaga and her manager Troy Carter are done. The reason is "creative differences."
Carter created Gaga's career in 2007 and got her a deal at Interscope. He was apparently cut out of the "ARTPop" album campaign and Gaga refused his advice.
It all came to a head the other night at the YouTube Awards when millions of people watched Gaga in the darkness singing a ballad called "Dope."
Carter manages John Legend and other artists.
