Jennifer Lopez engaged in pants-off yesterday.

But were they the tightest pants on stage? That question became a source of contention between Lopez and Fallon, who's silly little routine turned VERY serious when J. Lo threatened to "cut" her "bitch" of an opponent.
Wait.. what?!? Really?!? Watch this segment now... and be very afraid:
