The 6 Biggest Musician-Manager Feuds

3. Christina Aguilera

This superstar struggled with her bubble-gum pop image for several years before firing the man responsible for it: Steve Kurtz. When it was time for a creative change, Christina felt smothered by her ex-manager, who had previously overloaded her schedule, resulting in the singer’s complete exhaustion. So in 2000, Aguilera took matters into her own hands, firing Kurtz and hiring Irving Azoff in his place. She also filed a lawsuit against her former manager, accusing him of inappropriate influence over her professional activities, and fraud.
