In spite of Katy's highly publicized divorce from Russell Brand, the pop superstar remains on top of her game. In her first movie, "Part of Me," the superstar reveals that she did everything in her power to avoid the dissolution of her marriage, reports People. "I have that same belief system with everything, from career to my life to my personal life, everything. And I will do everything it takes to not fail.
