The Carmelo Anthony divorce from the Denver Nuggets is getting ugly.

One night after scoring 27 points in his Knicks debut at the Garden in a 114-108 win over the Bucks, Anthony took exception to comments his former head coach made during TNT’s broadcast of the Nuggets-Celtics game Thursday night.

“Melo is the best offensive player I’ve ever coached, but his defensive focus, his demand of himself is what frustrated us more than anything,” George Karl said in his brief sideline comments.

It didn’t take long for Anthony to fire back on his verified twitter account (@carmeloanthony).

The Denver Post reported that Anthony did not return a text when asked to comment about his tweets.
