"'Mi Reflejo' had been such a beautiful, special time in my life, but it was 20- plus years ago when I was coming on the scene. I was so green to the business. I was baby Christina," the singer said. "20 years later, I'm a grown woman who had such an incredible career. Now I get to come back having reflected on that."
Aguilera also said as a mother now, she relishes the chance to share her Spanish music with her kids because it's "a big part of them and who they are."
Two of the songs from "La Fuerza" are collaborations, something common in Latin music.
"Latin music is such a community-based, beautiful environment, and there's so much love there that I wanted to make it a unified experience," Aguilera told CNN en Español.
"It's more important to me now that I do things with artists who I not only admire, but I know I'm doing it because I love and want the experience. The experience outweighs any other thing to me. And at this point in my life and career, it's important for me to do things that I love to do and not for any other reason," the singer said.
In her first single, "Pa' Mis Muchachas," Aguilera surrounded herself with feminine powerhouses.
"I have so much admiration for other strong women and women who speak their truth," she said.
