Kevin Durant GOES CRAZY . . .Cusses out a fan . . . Who Says Some Very DISRESPECTFUL THINGS About His Fiance!!!

    Kevin Durant is very calm on the court . .. but when you mess with the woman he loves - PREPARE FOR HIS WRATH.

One very hateful hater took to Instagram to make a reckless comment about a photo of Monica Wright that KD posted on Instagram. KD Blacked OUT . . . saying that he would find who dude was . . . and come see him OFFLINE.

The commenter said that Monica Wright was really Rajon Rondo in a wig. Very disrespectful.

Good for Kevin . . .
