It looks like Gaga is playing the blame game when it comes to the lack of success of her recent album ARTPOP! She is blaming her former manager, Troy Carter! A source says, " She's mad the album failed. At no point does she talk about the under-performance of the music . . . Everything is to blame except the music being bad."As previously reported, Gaga took to her Little Monsters website and ranted about being betrayed. She wrote, "Those who have betrayed me gravely mismanaged my time and health and left me on my own to damage control any problems that ensued . . . Millions of dollars are not enough for some people. They want billions. Then they need trillions . . . Those who did not care about 'Artpop's' success are now gone . . . I never thought after all the years of hard work that those I called friends and partners would ever care so little at a time I needed them the most."
