Jimmy Fallon scored his one and only entry on the Billboard Hot 100 with "Ew!" the goofy teen-angst viral hit with will.i.am from 2014. (It reached No. 26.)
The late-night host has gone back to the source material, this time with Jennifer Lopez.
Fallon and Lopez get their piggy tails on as BFFs Sara and Gabby for a sketch full of selfies, moans about their "worst day ever" ("my dad joined SnapChat, and he friended me!") and a J.Lo twerk that will have viewers going...."ewwwwwww."
Watch the video below.
The two also played a game of Password with Khloe Kardashian and Questlove.
