Artist had 13-year relationship with Henry.

Superstar Madonna has split with her manager of seven years, Caresse Henry. The two have reached a mutual agreement to part ways, an artist spokesperson confirms.

Neither Madonna -- who is currently promoting her latest children's book "The Adventures of Abdi" -- nor Henry had any comment.

Henry, who had worked with the artist for 13 years in total, took on managing responsibilities for Madonna in 1997 after the star parted ways with Freddy DeMann, her manager since 1983. Henry managed Madonna alongside the Q-Prime company from 1997 through 1999, when she became the artist's sole manager.

Madonna and Henry were both winners at tonight's (Nov. 9) Billboard Backstage Pass touring awards. The artist's Reinvention Tour was honored as the top tour of the year and Henry received the top manager award, awarded to the person with the top-grossing artist or artists.

Produced by Clear Channel Entertainment (CCE), Re-Invention grossed $125 million from 56 performances, of which 55 were sold out. The trek was topped by a six-night stint at New York's Madison Square Garden that grossed nearly $13 million.
