Blige fracas caught on tape

Mary J. Blige is caught on camera in a blistering argument with her husband, Kendu Isaacs, at her record-release party Tuesday. Footage obtained by The Post shows Blige raising her hand in front of Isaacs. Witnesses told Page Six that the singer hit him in the face and left a bite mark on his hand at trendy downtown club M2. The video footage shows Isaacs being held back by a security guard, who blocks much of the shot, as Blige storms off. As we reported yesterday, the singer flipped out when she thought he was flirting with a waitress. A witness told us, “They got in each other’s face before someone tried to separate them, at which point she shoved the guy aside . . . and popped [Isaacs] in the face. Then she bit him on the hand.” Her rep responded, “People lie and don’t know what they are talking about.” But the video shows Isaacs looking down at his hand.
