Jennifer Lopez is out doing press, because she’s JLO and she stopped by The Tonight Show to talk about everything! Her relationship to A-Rod, and her favorite person to perform for (catch those videos below).

If you didn’t know, Jenny from the block is very competitive, so when the challenge is presented, she doesn’t back down. Jimmy proposed a dance-off, but fast style! The funny part comes in here…they have to dance fast to 80s slow songs! Watch the above video.
