Mary J. Blige's divorce from her estranged husband Kendu Isaacs is as messy as they come, but the singer has been trying to keep a cool head about things despite the drama in the tabloids. Well, until now.

At some point over the weekend, Mary's Twitter fingers appeared to get the best of her and she tweeted an f-bomb filled message about her ex to all her fans.

"F*ck Kendu Isaacs I f*cking hate him and his whole family," the tweet reads. "I unfollowed him on IG and all of mv fans need to."

Yikes. That kind of tweet is pretty uncharacteristic of Mary (at least nowadays), so it's not clear if she was hacked or just in an ultra petty mood. The tweet has since been deleted, but check out a screenshot for yourself, below:
