Jennifer Lopez Twerked to Rihanna's "Work" on 'The Tonight Show' Last Night

Jimmy Fallon's "Ew!" sketch is back in all its glory.

Jennifer Lopez guest-starred on The Tonight Show last night and helped Jimmy reboot his hilarious sketch by playing a teenage girl named Gabby. Sara "without an h," a.k.a. Jimmy, and Gabby (J. Lo) hung out in Sara's basement to shoot the sh-t about Snapchat and creepy dads. At one point, Sara announced that she and Gabby would put on an "Ew! Talent Show" and prompted Gabby to show off her talent: dancing.

Gabby pretended to be shy at first, but come on. Did you see J. Lo's American Music Awards performance a few months back? Sara put on Rihanna's latest banger "Work" and Gabby immediately let loose. And then, she twerked.

This is literally exactly what you want to do when you hear RiRi's song come on in the club, isn't it? Watch Jimmy x J. Lo's "Ew!" sketch in the clip below.
