This is the Lopezes second trip to the annual gala as nominees.
They previously attended in 2014 and went home with the Best Original Song Oscar for "Let It Go" from "Frozen."
The married artists have since written a dozen new songs for the Broadway musical version of "Frozen," which is now in previews.
Asked by UPI in New York recently if she was looking forward to heading to Hollywood for the Oscars, Anderson-Lopez replied: "Our category is a little nuts. It's really exciting. Bobby and I are taking the girls as our dates. So, for us, just being there with our girls, in the sunshine, in the middle of ['Frozen'] previews, is going to be such a good, like, lily pad of sanity. We have to go walk a red carpet and dress up, but we're going to just have fun no matter what happens."
"Coco," which is also up for the Best Animated Feature Oscar, is now available on DVD and streaming platforms.
