Citing "irreconcilable differences" as the reason for their split, MJB has also asked the judge to block Isaac's ability to get spousal support.
The divorce documents do not say if there is a prenup, and the couple has no children together. Blige listed the date of separation as "to be determined." Isaacs was also her manager.
UPDATE: Mary J. Blige's rep has released a statement to Us Weekly, saying, "Ms. Blige is saddened to say it is true that she has filed for divorce, saying sometimes things don't work how we hoped they would… but there is a divine plan and a reason for everything. Mary will continue writing and working on her album, which is due out later this year, along with her world tour. She thanks and appreciates her fans for their support and love through this very difficult emotional time."
