Lopez and Fallon started the segment titled The History of Music Video Dancing on Tuesday by busting a move to MC Hammer's "U Can't Touch This."
The pair then performed dance moves from The Bangles' "Walk Like an Egyptian," "Macarena," TLC's "Waterfalls," Britney Spears' "Oops!...I Did It Again," Beyonce's "Single Ladies (Put a Ring on It)," and Lady Gaga's "Bad Romance," among many others.
"She was like, 'I'll tell you what my mother-in-law told me on my wedding day, which was It's good to be a little deaf sometimes,'" Lopez said.
Lopez presented footage of her 11-year-old daughter Emme performing onstage with her during a recent tour.
"She just gets out there and she just does it. Nerves of steel," Lopez said about her daughter willing to perform a song with her mother on every night of the tour.
