Looks like Ben Affleck made his exit stage left early … leaving Jennifer Lopez to shine solo as the night raged on after their “Kiss of the Spider Woman” reunion.

Video doesn’t lie … J Lo was in full social butterfly mode at the NYC afterparty Monday … laughing it up and working the room, all with zero Ben in sight.

Now, Ben doesn’t pop up in these shots … but hey, he could’ve been lurking elsewhere at the bash — so we can’t say for sure he was a no-show at the after party.

Still, Jennifer looked like she had no shortage of company — laughing it up at the afterparty hours after the premiere, where she enjoyed the red carpet company of Ben — who serves as executive producer on the musical.
