While Jennifer Lopez and Marc Anthony dined at Eva Longoria's restaurant Beso an insane fight broke out in the streets outside.




The brawl erupted at Cinespace on Hollywood -- which is right by Beso -- where two groups punched, kicked and just generally beat the crap out of each other all over the block.

Marc and J.Lo eventually made their exit from Beso after the cops showed up and the fight died down.
