Mariah Carey splits with her manager

London: Singer Mariah Carey has parted ways with her manager-collaborator-producer Jermaine Dupri.

The `Hero` hitmaker hired her superproducer friend as her manager last autumn, but after less than a year in his new role, Dupri is stepping down from the position, reportedly. "I`m a very hands-on person when it comes to my work. I put my all into every project. But when I`m not allowed to do what I do, then I know it`s time for me to move on. Mariah and I enjoy working together and will continue to make great music together in the future," Dupri said in a statement. The split comes on the heels of the disappointing sales of Carey`s `Elusive Chanteuse`, which has only moved 103,000 units since its release in May. In addition to his role as executive producer of her latest album, the `So So Def` mogul produced two of Carey`s biggest hits to date -- `We Belong Together` and `Always Be My Baby`. Carey is now reportedly working closely with Kevin Liles, who currently manages Ty Dolla Sign and Trey Songz.
