James Harden is being CALLED OUT by Khloe Kardashian -- who says James begged her to be in an exclusive relationship ... only to CHEAT ON HER ASS!
KK put Harden on blast on "Kocktails with Khloe" on FYI -- saying the Houston Rockets star was so into her, that he sweet talked her into monogamy -- and then screwed her over.
"He sought me out, He wanted to be committed ... then wasn't committed."
