Jennifer Lopez mixed work with pleasure on American Idol last night when she hit the stage alongside her boyfriend, Casper Smart.

We all know that Lopez has no problem dating (or marrying) her backup dancers and she proudly flaunted her young lover on the Idol stage during a performance of her new single, “Dance Again.” Isn’t young love so adorable? Wait, we almost forgot, Lopez is in her 40s.

Well, as Lopez’s body proves, age is just a number, so we won’t judge. Watch her perform on Idol below:
