Jennifer Lopez is a talented dancer and her boyfriend Casper Smart, 25, is also a talented dancer, so what happens when you get two people who love to dance together in a dance studio? One insane workout! Casper and Jennifer spent four hours together in dance rehearsals on Saturday afternoon!

Casper and Jen rehearsed in Hollywood before going to Aroma Cafe in Beverly Hills for lunch. At least they’re both into the same things? Casper and Jen’s new video is so sexual, it’s been called “skanky.”
