4. Splitting with her manager Troy Carter
It's never a good sign when you split with a manager -- who helped make you a star -- only a week away from the release of your new album. "Creative differences" have been the pullquote over the parting-of-ways, though more reports indicate Carter's input was snipped early on in the "Artpop" cycle. Gaga obviously had a vision for "Artpop": Carter could have been cut out of the loop because he didn't share or like that vision, or had no way to help her translate that vision to the masses. Or it could be that managers, in many cases, can be an artist's only source of "no" when all others say yes and that no longer flies for the pop singer. For a man who helped her sell millions of albums, and send her on some of the most tight, best-selling concert tours of the past decade, Carter's role as a "no-man" seems to be fairly important, especially with a challenging new era in Lady Gaga's lifeline.
