Is Kendu cheating on Mary?

According to not so reputable Mediatakeout.com, the Queen of R&B Mary J. Blige's marriage might be in shambles, they are saying her husband Kendu Isaacs has been cheating on her:

"A close friend of the couple told MediaTakeOut.com that Mary suspects that her husband has been cheating. According to our source, "Mary caught him doing something that he shouldn't have been doing and she is mad as hell." And the source added, "for Mary, there's nothing worse than being betrayed ... so I think the marriage is probably over.""

I'm hoping this isn't true because I really love Mary and have been happy that she'd finally found a good man, I remember hearing she was trying to get pregnant, now this.....Source.
