Michael Bisping is SPITTIN' FIRE ... takin' aim at Luke Rockhold and Demi Lovato's relationship ... saying Rockhold could never get a girl with "intelligence" ... and it's all on video!!
TMZ Sports talked to Bisping outside the UFC Gym in Torrance ... and he absolutely went off.
Rockhold and Lovato weren't the only ones in his crosshair ... he also takes on Dan Henderson ("I'm going to embarrass him") and Conor McGregor's fashion sense ... or lack of.
The video is incredible ... check it out!
