Mary J. Blige has filed for divorce from her husband and former manager, Kendu Isaacs, her representative has confirmed to USA TODAY.

“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,” her publicist Karynne Tencer said in a statement. “But there is a divine plan and a reason for everything.”

The couple, married for 12 years, had no children together, though Blige was a stepmother to Isaacs’ children from a past relationship, Briana, Jordan and Nas.

The singer cited irreconcilable differences as grounds for divorce in court documents obtained by TMZ and subsequent outlets.

“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,” Tencer said.

Blige, 45, has been candid about the pros and cons of marrying her manager, telling The Telegraph in 2014 that although she felt Isaacs always “had her back,” the downside “is that there’s no separation — it’s on all the time. When you don’t feel like answering to your manager, he’s still your husband.”
