Michelle Rodriguez upstaged the NY Knicks from her courtside seats by drunkenly posing for ridiculous selfies ... and snuggling up to smoking hot model Cara Delevingne.

Michelle was all over Cara -- and looked totally out of it -- while putting on what has to be the greatest party chick clinic in NBA history last night at Madison Square Garden.

It's unclear if Michelle -- who's proudly stated going "both ways" in the past  -- scored after the game ... but click through the gallery.

Looks to us like Michelle put in enough work to earn some overtime. 

Oh, the Knicks won the game. But who cares?
