Lopez teased a show that will feature all her pop hits while embracing "my Latin side, my fun side, and my hip-hop side."
"It's gonna have everything that I've been known to do over the years, and it's gonna be a beautiful, glamorous kind of Vegas show," she said. "Something that I think people, whether you're a fan of my music or not, would come and see and really enjoy. That's my goal."
But first, the pressure is on to make American Idol's farewell season the best one yet.
"I think [it's] just a really exciting season," she said. "We'd rather have an extraordinary tight group of kids than a bunch of kind of good [ones]. -- OK, we're not going for good this year -- we're going for over the top!"
American Idol season 15 will air on FOX this fall.
